Step-by-step explanation:

[tex](+)(+)=(-)(-)=(+)\\(+)(-)=(-)(+)=(-)\\\\-(-x-3)=-1(-x-3)\qquad\text{use the distributive property}\\\\=(-1)(-x)+(-1)(-3)=x+3[/tex]

The numbers are -3 and 2

Step-by-step explanation:

Let x be the first number and y be the second number

then according to given statements the linear equations will be:

"Four times a number minus twice another number is -16"

[tex]4x-2y = -16\ \ \ Eqn1[/tex]

"The sum of the two numbers is -1"

[tex]x+y = -1\ \ \ Eqn2[/tex]

From equation 2:

[tex]y = -x-1[/tex]

Putting y = -x-1 in equation 1

[tex]4x-2(-x-1) = -16\\4x+2x+2 = -16\\6x +2 = -16[/tex]

Subtracting 2 from both sides

[tex]6x+2-2 = -16-2\\6x = -18[/tex]

Dividing both sides by 6

[tex]\frac{6x}{6} = \frac{-18}{6}\\x = -3[/tex]

Putting x = -3 in equation 2:

[tex]x+y = -1\\-3+y = -1\\y = -1+3\\y = 2[/tex]

Hence,

The numbers are -3 and 2

Find the total miles of all 3 trucks:

790 + 830 + 948 = 2568

Divide the total by the 12 miles per gallon to find total

Gallons used:

2568 / 12 = 214 total gallons

Multiply total gallons by price:

214 x 1.60 = 342.40

Total amount = $342.40

Answer:

How many boys are there in total? We can't answer correctly until you give us all the information.

Step-by-step explanation:

The percentage of students who like both oranges and apples (x%) is equal to or greater than 34%.

Let's start by representing the students who like oranges as set A and the students who like apples as set B. We are interested in finding the percentage of students who like both oranges and apples, which corresponds to the intersection of sets A and B.

Based on the given information:

Percentage of students who like oranges (A): 70%

Percentage of students who like apples (B): 64%

Percentage of students who like both oranges and apples (x%): ?

Now, let's use set theory notation to represent the information:

A = students who like oranges

B = students who like apples

A ∩ B = students who like both oranges and apples

The total percentage of students who like oranges or apples can be calculated using the principle of inclusion-exclusion:

Percentage(A ∪ B) = Percentage(A) + Percentage(B) - Percentage(A ∩ B)

We know that Percentage(A) = 70% and Percentage(B) = 64%. Let's denote Percentage(A ∪ B) as y% for simplicity.

y% = 70% + 64% - x%

y% = 134% - x%

Since the total percentage cannot exceed 100% (as it represents the whole student population), we can conclude that:

y% ≤ 100%

134% - x% ≤ 100%

x% ≥ 34%

So, the Main Answer is x% ≥ 34%

The number of ways Kelly can choose 5 markers from 16 markers is calculated by Combinations

And , the combination is given by

¹⁶C₅ = 16! / ( 16 - 5 )! ( 5! )

On simplifying the equation , we get

¹⁶C₅ = 16! / 11! x 5!

¹⁶C₅ = ( 16 x 15 x 14 x 13 x 12 ) / ( 5 x 4 x 3 x 2 x 1 )

The value of ¹⁶C₅ = 4368 ways

Therefore , the value of A is 4368 ways

Hence , The number of ways 16 colored markers in bucket can be arranged by Kelly if she chose 5 of them is 4368 ways

40 kilograms alloy of 20 % copper and 60 kilograms of alloy of 70 % copper is combined to get 100 kg of 50 % copper alloy

Solution:

Th final alloy is 100 kg

Let "x" be the alloy of 20 % copper

Then, (100 - x) is the alloy of 70 % copper

Therefore,we can say,

"x" kilograms alloy of 20 % copper and (100 - x) kilograms of alloy of 70 % copper is combined to get 100 kg of 50 % copper alloy

Therefore, we frame a equation as:

[tex]x \times 20 \% + (100-x) \times 70 \% = 100 \times 50 \%\\\\x \times \frac{20}{100} + (100-x) \times \frac{70}{100} = 100 \times \frac{50}{100}\\\\0.2x + (100-x) \times 0.7 = 0.5 \times 100\\\\0.2x + 70 - 0.7x = 50\\\\-0.5x = -20\\\\x = 40[/tex]

Thus 40 kilograms of 20 % copper

Then, 100 - x = 100 - 40 = 60

60 kilograms of 70 % copper is used

Answer:

Clara drew the figure correctly and correctly identified the four-sided figure as a quadrilateral.

Step-by-step explanation:

To plot the vertices of the figure, Clara needs to take the first coordinate of each point and mark it on the x-axis and the second coordinate should be marked on the y-axis. Then she has to draw vertical and horizontal lines through the x-coordinate and y-coordinate. These two lines intersect at the point which has those coordinates. Following these steps, Clara drew the figure correctly.

Connecting all consecutive vertices, she got a figure with four sides - this is exactly the quadrilateral.

Hence, Clara drew the figure correctly and correctly identified the four-sided figure as a quadrilateral.

Therefore the probability of Maria scoring on her next shot is [tex]\frac{1}{4}[/tex].

Step-by-step explanation:

i) Maria scored two goals and missed on her other six shots.

ii) Maria took a total of eight shots on the goal.

iii) On an average Maria scored twice in every eight shots or once in every four shots on the goal. So we can say that the probability of Maria scoring a goal on every shot on goal is one in four or [tex]\frac{1}{4}[/tex].

iv) Therefore the probability of Maria scoring on her next shot is [tex]\frac{1}{4}[/tex].

y = 5x + 4 is the equation of the line whose slope is 5 and y intercept is (0,4)

Solution:

Given that we have to write the equation of the line whose slope is 5 and y intercept is (0,4)

The equation of line in slope intercept form is given as:

y = mx + c -------- eqn 1

Where, "m" is the slope of line and "c" is the y - intercept

Given that,

Slope = m = 5

Also, y intercept is (0,4)

Therefore, c = 4

Substitute c = 4 and m = 5 in eqn 1 to get equation of line

y = 5x + 4

Thus the equation of line is found

Answer:

The cost for full day car rental will be $100.

Step-by-step explanation:

A bike shop charges x dollars to rent a bike for half a day. It charges (x + 40) dollars to rent a bike for a full day.

On that day the shop made a total of $600 from the bike rentals. If there were 5 half day and 3 full day rental, then we can write

5x + 3(x + 40) = 600

⇒ 8x = 600 - 120

⇒ 8x = 480

⇒ x = $60

Therefore, the cost for full day car rental will be $(x + 40) = $100. (Answer)

Answer:

Unpaid balance = $ 250.22

Finance charge = $ 3.13

New balance = $ 348.60

Step-by-step explanation:

Calculate the unpaid balance, finance charge, and new balance using the unpaid balance method.Note: interest rate is given as a monthly rate.

Previous balance = $410.22

Payments/credits = $160.00

subtract 410-160 to get unpaid balance

Unpaid balance = $ 250.22

Monthly rate = 1.25%

multiply 250 by monthly rate (decimal) .0125 to get finance charge

Finance charge = $ 3.13

New purchases = $95.25

add unpaid balance and finance charge and new purchases to get new balance

New balance = $ 348.60

Final answer:

To calculate the unpaid balance, finance charge, and new balance using the unpaid balance method, subtract the payments/credits from the previous balance, add the finance charge, add the new purchases, and calculate the new balance.

Explanation:

To calculate the unpaid balance, finance charge, and new balance using the unpaid balance method, follow these steps:

Start with the previous balance.

Subtract the payments/credits.

Add the finance charge.

Add the new purchases.

Calculate the new balance.

For example, with a previous balance of $410.22, payments/credits of $160.00, and new purchases of $95.25, the equation would be: unpaid balance = previous balance - payments/credits = $410.22 - $160.00 = $250.22. The finance charge would then be calculated by multiplying the unpaid balance by the monthly interest rate. Finally, the new balance would be the unpaid balance plus the finance charge and new purchases.

Answer: a combination of 75 adult tickets and 250 student tickets would make $2000

Step-by-step explanation:

A theater wants 2000$ and children’s tickets cost 5$ and adult tickets cost 10$. To find a combination of children and adult tickets that will make 2000$, we would assume a value for either the number of student tickets or adult tickets and assume a variable for the other.

Assuming 250 student tickets and x adult tickets were sold. Therefore,

250 × 5 + 10x = 2000

1250 + 10x = 2000

10x = 2000 - 1250 = 750

x = 750/10 = 75

Answer:

The sum of the two equations is 8x + 5 and the value of x is -5/8

Step-by-step explanation:

Let's add these two equations and solve for x:

2x + 6 + 6x - 1 = 0

8x + 5 = 0

8x = -5

x = -5/8

The sum of the two equations is 8x + 5 and x =  -5/8

Answer:

Sum = 8x + 5

Step-by-step explanation:

It is required to add the following equations

2x+6    &   6x-1

So, the sum of the equations

= (2x + 6) + ( 6x - 1 ) ⇒ Combine like terms.

= ( 2x + 6x ) + ( 6 - 1 )

= 8x + 5

So, the result of adding the equations 2x+6 and 6x-1 is 8x + 5
