Answer:

4

Step-by-step explanation:

A term no matter how long it is, is ended by some sort of sign. so 6 is a term 2x is a term -4y is a term and 5z is a term. The term could be 5xyz^6a^2bc^7 + 2, and there are only 2 terms.

Answer:

4

Step-by-step explanation:

There are 4 terms in the expression.  Terms are separated by the addition or subtraction sign.

Answer: z < 4

z+4 > 2z

z+4-z > 2z-z ..... Subtract z from both sides

4 > z

z < 4

So the solution set for z is any number that is less than 4, which could be something like z = 2 or z = 3.

Answer:

the solution is (3,4) (the second one)

Step-by-step explanation:

The correct graph is attached to the answer.

The amount of fruit syrup Rex added is: 3 liters

and the amount of water he added is: 4 liters.

x denote the amount of fruit syrup added and y denote the amount of water added.

It is given that:

Three times the number of liters of water he mixed was 6 more than twice the number of liters of syrup he mixed.

i.e. the equation that satisfies this condition is:

         [tex]3y=2x+6\\\\i.e.\\\\2x-3y=-6-----------(1)[/tex]

i.e. the graph of this equation is a line that passes through (-3,0) and (0,2)

Also, The total number of liters of syrup and water he mixed was 7 liters.

Hence, the equation is:

                       [tex]x+y=7------------(2)[/tex]

i.e. the graph of this equality is a line that passes through (7,0) and (0,7)

Also, from equation (2) we have:

[tex]x=7-y[/tex]

Now, on putting this value of x in terms of y in equation (1) we get:

[tex]2(7-y)-3y=-6\\\\i.e.\\\\14-2y-3y=-6\\\\i.e.\\\\14-5y=-6\\\\i.e.\\\\14+6=5y\\\\i.e.\\\\5y=20\\\\i.e.\\\\y=4[/tex]

Also, on putting the value of y in equation (2) we get:

[tex]x=3[/tex]

Hence, the solution to the system of linear equation is:

                 (3,4)

The ratio of the triangle is 55/1.1, which is 50/1.

This means that the building is 50/1 = x/5

x = 250

The office building is 250 m tall.

The height of the office building is calculated using similar triangle ratios, by setting up a proportion between the tree's dimensions and the building's shadow, and solving for the building's height to get 250 meters.

To calculate the height of the office building using similar triangle ratios, compare the tree's height and shadow length to those of the building. Since the tree is 5 m tall and casts a 1.1 m long shadow, we can set up a proportion with the building's shadow, which is 55 m long.

Step-by-step calculation:

Write the proportion using the tree's height and shadow: 5 m (tree height) / 1.1 m (tree shadow) = building height / 55 m (building shadow).

Cross multiply to find the building's height: 5 m × 55 m = 1.1 m × building height.

Perform the calculations: 275 m² = 1.1 m × building height.

Divide both sides by 1.1 m to solve for building height: building height = 275 m² / 1.1 m.

Complete the division: building height = 250 m.

Simplifying

2.1x + -1(1 + 4.2x) = 5.3

2.1x + (1 * -1 + 4.2x * -1) = 5.3

2.1x + (-1 + -4.2x) = 5.3

Reorder the terms:

-1 + 2.1x + -4.2x = 5.3

Combine like terms: 2.1x + -4.2x = -2.1x

-1 + -2.1x = 5.3

Solving

-1 + -2.1x = 5.3

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '1' to each side of the equation.

-1 + 1 + -2.1x = 5.3 + 1

Combine like terms: -1 + 1 = 0

0 + -2.1x = 5.3 + 1

-2.1x = 5.3 + 1

Combine like terms: 5.3 + 1 = 6.3

-2.1x = 6.3

Divide each side by '-2.1'.

x = -3

Simplifying

x = -3

Answer:

56

Step-by-step explanation: You have to substitute 6 for a because it says, "Which expression is equivalent to 7(a+2) when a=6"

7(a + 2)

7(6 + 2)

42 + 14

= 56

To find the equivalent expression to 7(a+2) when a=6, substitute the value of a into the expression to get 56.

To find the expression equivalent to 7(a+2) when a=6, we substitute the value of a into the expression:

7(a+2) = 7(6+2)

7(6+2) = 7(8)

7×8 = 56

Therefore, the expression equivalent to 7(a+2) when a=6 is 56.

Answer:

(B) Revenue account which increases

Step-by-step explanation:

Hello, my dear friend, I am sure the question you are intending should be corrected as follows:

In transaction (C) on 5/10, the Fees Earned account is a(n) A. Expense account, which increases B. Revenue account, which increases C. Revenue account, which decreases D. Asset account, which decreases

If that is the case, then please note that whatever amount you earn, is an amount that will always increase. If you have no earnings, then nothing decreases nor decreases.

The Fees Earned account is a type of revenue account that increases when the company earns more fees. Therefore, option B (revenue account, which increases) is correct.

In transaction (C) on 5/10, the Fees Earned account is usually classified as a revenue account. Therefore, when a company earns fees, it records the transaction as an increase in the fees earned account. The more fees the company earns, the higher the balance in this account, representing the income the company has made. So, if the Fees Earned account is increasing in value, it would be correct to say that it is a revenue account, which increases. This makes option B the correct answer.

Answer:

D. -27+15 (N-1)

Step-by-step explanation:

-27, -12, 3, 18

Take the second term and subtract the first term to find the common difference

-12 - (-27)

-12+27 = 15

The common difference is +15

We are adding 15 each time

The formula for an arithmetic sequence is

an = a1+d(n-1)

an = -27 +15(n-1)

The correct nth-term expression for the given sequence is -27 + 15(n - 1), reflecting the sequence's consistent increase of 15 between terms.  So the correct option is D.

The student's question asks for the expression that defines the nth term of the sequence -27, -12, 3, 18, ... given that a1 = -27. Observing the sequence, we can see that each term increases by 15 from the preceding term. Thus, to find the nth term, we start with the first term (-27) and add 15 to it n times (n - 1), because the first term is already included.

The correct expression for the nth term is therefore -27 + 15(n - 1), which simplifies to -27 + 15n - 15 and further simplifies to -42 + 15n. This corresponds to option D: -27 + 15 (n - 1).

You must find the common denominator for all of them.  

A is correct. 13 x 2 is 26 and 14 x 2 is 28. Therefore, 13/14 is greater than 25/28.

B is not correct. 4 x 5 is 20 and 9 x 5 is 45. 4/9 is actually less than 21/45.

C is not correct. 5 x 2 is 10 and 6 x 2 is 12. 5/6 is actually less than 11/12.

D is not correct. 4 x 5 is 20 and 5 x 5 is 25. 4/5 is actually less than 8/25.

Answer:

The only value I can see that won't work is a = 0. That value gives you 0 over 0 which has no definite answer at this level. It is best to call such a thing undefined or not permitted.

The measures of the angles and side lengths are:

m∠ BED = 130°

m∠ BEA = 50°

x = 7

y = 16.4

BE ≈ 23

BC ≈ 34

8. m∠ BED

∠DEB and ∠BED are supplementary angles, so their measures add up to 180°.

Therefore, m∠BED = 180° - m∠DEB = 180° - 50° = 130°.

9. m∠ BEA

∠BEA and ∠DEB are vertical angles, so they have the same measure. Therefore, m∠BEA = m∠DEB = 50°.

10. x

We can use the fact that the sum of the angles in a triangle is 180° to find x.

In triangle ABE, we have ∠BAE + ∠ABE + ∠BEA = 180°.

Substituting the given values, we get (7x - 2)° + 80° + 50° = 180°.

Solving for x, we get 7x = 50, so x = 7.

11. y

We can use the fact that the measures of the angles in a triangle add up to 180° to find y.

In triangle BCE, we have ∠BCE + ∠BEC + ∠CEB = 180°.

We are given that ∠BCE = 20° (since ∠BDE = ∠BCE, and we found m∠BDE in part 8), and we can find ∠BEC using the fact that it is supplementary to ∠BEA (which we found in part 9).

Therefore, ∠BEC = 180° - 50° = 130°.

Substituting these values, we get 20° + 130° + ∠CEB = 180°.

Solving for ∠CEB, we get ∠CEB = 30°.

Now, we can use the fact that ∠CEB and ∠DEB are vertical angles to find that ∠DEB = 30°.

Finally, we can use the fact that the sum of the angles in a triangle is 180° to find y in triangle BCD.

We have ∠BCD + ∠CDB + ∠DBC = 180°.

Substituting the given values, we get 30° + 90° + (5y - 22)° = 180°.

Solving for y, we get 5y = 82, so y = 16.4.

12. BE

We can use the Pythagorean theorem to find BE in triangle ABE.

We have AB^2 = AE^2 + BE^2.

Substituting the given values, we get (5y - 22)^2 = (3y)^2 + BE^2.

Simplifying, we get 25y^2 - 220y + 484 = 9y^2 + BE^2.

Solving for BE^2, we get BE^2 = 16y^2 - 220y + 484.

Substituting the value of y that we found in part 11, we get BE^2 = 16(16.4)^2 - 220(16.4) + 484 ≈ 531.4.

Taking the square root of both sides, we get BE ≈ 23.

13. BC

We can find BC using the Pythagorean theorem in triangle BCE.

We have BC^2 = BE^2 + CE^2.

Substituting the values we found for BE and CE, we get BC^2 = 23^2 + (3y)^2.

Substituting the value of y that we found in part 11, we get BC^2 = 23^2 + 3(16.4)^2 ≈ 1163.

Taking the square root of both sides, we get BC ≈ 34.

Final answer:

To find the length of X, we can use the concept of corresponding sides in similar figures. By establishing the ratio between corresponding sides AB and PQ, we can find the length of X. The length of X is found to be 2 units.

Explanation:

In order to find the length of X in the similar quadrilaterals ABBCD and PQRS, we need to find the corresponding sides that are proportional to each other. Let's say AB represents a side of ABBCD and PQ represents the corresponding side of PQRS. If AB is 6 units long and PQ is 3 units long, then the ratio of AB to PQ is 6:3, which simplifies to 2:1. Since the lengths of corresponding sides in similar figures are proportional, if AB has a length of 4 units, then PQ would have a length half of that, which is 2 units. Therefore, the length of X is 2 units.

Step-by-step explanation:

so multiply 7.9 * 8.6 which will give you 67.94

Answer:

The area is 67.94m.

Step by Step Explanation:

16. x - 4 = 4

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides:

x - 4 (+4) = 4 (+4)

x = 4 + 4

x = 8

17. a/4 = 4

Isolate the variable (a). Note the equal sign, what you do to one side, you do to the other. Multiply 4 to both sides:

(a/4)(4) = (4)(4)

a = (4)(4)

a = 16

18. y * 20 = 30

Isolate the variable (y). Note the equal sign, what you do to one side, you do to the other. Divide 20 from both sides.

(y *20)/20 = (30)/20

y = 30/20

y = 3/2 or 1.5

19. x/5 = 20

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Multiply 5 to both sides

(x/5)(5) = (20)(5)

x = (20)(5)

x = 100

Answer:

x = 26, y = 9

Step-by-step explanation:

Let one number be x, and the other be y. Set the equations:

x + y = 35

x - y = 17

First, isolate the x in the first equation. Subtract y from both sides

x + y (-y) = 35 (-y)

x = 35 - y

Plug in 35 - y for x in the second equation

(35 - y) - y = 17

35 - 2y = 17

Isolate the variable. Note the equal sign, what you do to one side you do to the other side. Do the opposite of PEMDAS. First, subtract 35 from both sides

35 (-35) - 2y = 17 (-35)

-2y = -18

Isolate the variable (y). Divide -2 from both sides

(-2y)/-2 = (-18)/-2

y = -18/-2

y = 9

Plug in 9 for y in one of the equations.

x + y = 35

x + 9 = 35

Isolate the variable (x). Subtract 9 from both sides

x + 9 (-9) = 35 (-9)

x = 35 - 9

x = 26
