Answer:12+6

Step-by-step explanation:

first set the first equation equal to x

subtract 2y from both sides

x=27-2y now plug this in to the other equation

2(27-2y)+3y=46 distribute

54-4y+3y=46 --> 54-y=46 now subtract 54 from both sides -y=-8 --> D)y=8

If you weren't asked to show work you could just plug the choices given into the equation

Final answer:

By using the elimination method and subtracting the second given equation from the doubled first equation, we find that the solution for y in the system of equations is y=8.

Explanation:

We are tasked with finding the solution for y in the system of equations:

x + 2y = 27

2x + 3y = 46

To solve the system, we can use either the substitution method or the elimination method. Let's use the elimination method for this problem:

Multiply the first equation by 2:

(2)(x + 2y) = (2)(27)

2x + 4y = 54

Now we have:

2x + 4y = 54 (from step 1)

2x + 3y = 46 (original second equation)

Subtract the second equation from the first:

(2x + 4y) - (2x + 3y) = 54 - 46

y = 8Thus, y=8 is the solution to the system of equations, which corresponds to option D.

There is no solution

There are no values of x that will make the equation true.

Answer:

$90

Step-by-step explanation:

Look at the number 7 on the bottom right of the graph. That means at the end of 7 weeks. Now look vertically up from there until you see a point directly above 7 weeks. Look to the left of that point, and you see that the point directly above 7 weeks is at the level of $90. That means that at the end of 7 weeks, he had $90.

Your answer would be Only B

Table A has a repeated number in the inputs, while Table B does not

In the tables, only B represents functions.

A function is a relation in which each domain value has only one range value. If a domain has more than one image in the range, it is not a function.

Observe table A.

We can see that the input value of 2 has two outputs.

This means that table A is not a function.

Observe table B.

In table B, all input values have one and only one output value.

This table represents a function.

Therefore we have found that, from the given tables, only B represents functions. The correct answer is option B.

Answer:

GH

Step-by-step explanation:

If you look at y = -2, you can see that AB is one unit below it. Now if you flip this line segment across y = -2, all you have to do is count on unit up and find segment GH is in the correct position.

Answer:

The line segment GH is the answer.

Step-by-step explanation:

In the given figure we can see that point B of line AB lies one unit below the given y=-2. Now, when this line across y = -2, the point B will lie one unit above -2 that is H with the other end G.                                                

So, GH is the correct answer.

Answer:

y = 6√3 and x = 6

Step-by-step explanation:

this is a 30-60-90 triangle.  The side opposite the 30° angle corresponds to the side of length 1  in the most basic 30-60-90 triangle; the side opp. 60° to the side of length √3; and the hyp. to the side of length 2.

To find y, write and solve an equation of ratios, as follows:

adj side           adj side      (adjacent to the 30° angle)

    y                       √3

 hypo               hypo    then (cross multiplying):  2y = 12√3, and

    12                     2       y = 6√3

If the hypo here is 12 and the adj side (y) is 6√3, then we can use the Pyth. Theorem to find the third side (x):

[12]² = [6√3]² - x²  ↔ 144 = 36(3) - x²   ↔  36 = x².  So x = 6 here.

Answer:

x = 6

y ≈ 10. 40

Step-by-step explanation:

Using the SOHCAHTOA principle we can solve for x and y since the angle is known and it is a right angle triangle.

hypotenuse = 12

adjacent = x

opposite = y

cos 60° = adjacent/hypotenus

cos 60° = x/12

cross multiply

x = 12 cos 60°

x = 12 × 0.5

x = 6

Finding y

sin 60° = opposite/hypotenuse

sin 60° = y/12

cross multiply

y = 12 sin 60°

y  = 12 × 0.8660254038

y =  10.392304845

y ≈ 10. 40

A = [Pi*r^2]/2

A = 60.5*Pi

A = 189.97 inc2

Best regards

Answer:

190 Square inches

Step-by-step explanation:

Formula for a semicircle is A=3.14*r^2/2

R=11 because its half the diameter

11^2=121

121 * 3.14 = 379.94

379.94 / 2 = 189.97

189.97 is approximately 190.

Answer:

13.6

Step-by-step explanation:

Add all of the ages up:

14 + 14 + 13 + 13 + 13 + 15 + 14 + 14 + 13 + 13 = 136

Then divide that by 10:

136/10 = 13.6

To calculate the mean absolute deviation of the ages in Mrs. Kiperling's class, first calculate the mean, then the absolute differences between each age and the mean, and finally average those differences to get an MAD of 0.6 years.

The mean absolute deviation (MAD) of a set of numbers is a measure of how spread out the numbers are from the average (mean). To calculate the MAD, we first find the mean of the data set, then find the absolute differences between each data point and the mean. Finally, we average those absolute differences to get the MAD. In this case, we begin by calculating the mean of the student ages:

Mean age = (14 + 14 + 13 + 13 + 13 + 15 + 14 + 14 + 13 + 13) / 10 = 13.6

Next, we find the absolute differences from the mean for each age:

Now we calculate the mean of these absolute differences:

MAD = (0.4 + 0.4 + 0.6 + 0.6 + 0.6 + 1.4 + 0.4 + 0.4 + 0.6 + 0.6) / 10 = 6 / 10 = 0.6

So, the mean absolute deviation of the student ages in Mrs. Kiperling's class is 0.6 years.

Answer:

814

Step-by-step explanation:

there has to be a number between 4,8

so either 4 can be at hundred position or 8 can be at hundredth position.

but since 1 comes before 4, then 1 has to be at tens place and 4 has to be at one's place.

so number is 814

Using the given clues, we can determine that the three-digit mystery number with digits 1, 8, and 4, where 1 comes before 4 and 4 is not next to 8, is 184.

The mystery number is a three-digit number where the digits are 1, 8, and 4. With the given clues that the digits 4 and 8 are not next to each other and that 1 comes before 4, we must arrange the digits accordingly.

Since we are told the exact sequence for 1 and 4, with 1 coming before 4, and knowing that 8 cannot be next to 4, the possible arrangement is: the digit 1 first, then 8, and finally 4.

Following these conditions, the mystery number is 184.

Answer:

Terminating decimal.

0.67 ends after the 7; therefore it's terminating.

A recurring decimal does not end.

Answer:

d

Step-by-step explanation:

To eliminate the fractions in the equation multiply all term on both sides by the lowest common multiple of 2 and 3, that is 6

3x + 18 = 4x + 6 ← equation with no fractions

Subtract 4x from both sides

- x + 18 = 6 ( subtract 18 from both sides )

- x = - 12 ( multiply both sides by - 1 )

x = 12 → d

Answer:

50.27 square inches

Step-by-step explanation:

If you look at the logo for the Super Snacks Company, you'll see it's basically a cylinder that has been cut and twisted, but if you just curve the top part the other way around, you'll have a perfect cylinder again.

We can then calculate the lateral surface area of the cylinder, to do so we use the following formula:

L = 2 * π * r * h

Which means we multiply by 2 by the constant π (3.1416) by the radius of the cylinder (in our case 2 inches, since the full diameter is 4 inches) and the height (in our case 4 inches).  So, we enter the numbers in the formula and solve it:

L = 2 * 3.1416 * 2 * 4 = 50.2656 square inches.

Step-by-step explanation:

use pemdas to eliminate parethesis then add them together

Answer:

1. 42 + t/6

2. 42 + 12/6

3. 42 + 2

4. 44

Step-by-step explanation:

-You start of with 42 + t/6. If t = 6

-If t = 6, the next step should be to replace t with 12 So it would be 42 + 12/6.

-If we have 12/6 we know to divide. 12 divided by 6 is 2. So we would replace 12/6 with 2. Now we have 42 plus 2

-42 plus 2 is 44.

The answer would be A. 198 cm. To find the circumference of a circle you take c=2piR. You would find the circumference of the bigger wedges and divide by 2 since it makes up 1/2 the circle. Then you would do the same for the smaller wedges and it would be approximately 198 cm

y=5x is your answer :)

The equation of the line passing through the points (1, 5) and (2, 10) is y = 5x.

Step 1: Calculate the slope (m) using the given points (1, 5) and (2, 10).

The slope (m) is given by the difference in y-coordinates divided by the difference in x-coordinates:

m = (10 - 5) / (2 - 1) = 5 / 1 = 5

Step 2: Select one of the points to use in the point-slope form. Let's choose (1, 5) as (x₁, y₁).

Step 3: Substitute the values into the point-slope form equation:

y - 5 = 5(x - 1)

Step 4: Distribute and simplify the equation:

y - 5 = 5x - 5

Step 5: Isolate 'y' on one side of the equation:

y = 5x - 5 + 5

y = 5x
