Answer:

2:3

Step-by-step explanation:

x + y = 5      ----->      y = 5 - x

x - 2y = -1

x - 2(5 - x) = -1

x - 10 + 2x = -1

3x - 10 = -1

3x = 9

x = 3

(3) + y = 5

y = 2

Solution to this system: (3,2)

Ratio of y to x = 2:3

Answer:

7 boxes

Step-by-step explanation:

Debra needs to fit 322 programs into boxes and each box can contain 48. Therefore, we must divide 322 by 48.

322 ÷ 48 ≈ 6.71

We need at least 7 boxes to contain the 322 programs because if we only have 6, then the remaining programs won't be in a box. Therefore, we have to round up to get 7 boxes.

Answer:

150 sq. in.

Step-by-step explanation:
Because... Suppose the planned dimensions of a rectangular kitchen have a length-to-width ratio of 3 to 2. The length of the original kitchen is 6z feet. The original kitchen can be made larger by adding four feet to each original dimension. Write a polynomial expression that represents the floor area of the larger kitchen in square feet.

The polynomial expression that represents the floor area of the larger kitchen in square feet is  24z² + 40z + 16

The area of Rectangle is length times of width.

The length-to-width ratio of the original rectangular kitchen is 3 to 2.

Let the width of the original kitchen "w".

Then the length of the original kitchen is length = 3/2×w

We are also told that the length of the original kitchen is 6z feet. We can use this information to solve for the width of the original kitchen:

6z = 3/2×w

w = 4z

So the width of the original kitchen is 4z feet.

To make the kitchen larger, we add four feet to each original dimension. The new length is:

length = 6z + 4 feet

width = 4z + 4 feet

Area = (6z + 4 feet) × (4z + 4 feet)

Multiplying out the terms, we get:

Area = 24z² + 40z + 16 square feet

Therefore, the polynomial expression that represents the floor area of the larger kitchen in square feet is  24z² + 40z + 16

An absolute value inequality that has a solution set -1<=x<=3 is |x-1| <= 2

The set of values of the variable involved in the inequality for which the considered inequality holds true is called the solution set for that inequality.

We've to find an absolute value inequality that has the solution set

-1 <= x <= 3

1+2 = 3

and 1 - 2 = 3

Therefore, we can rewrite the considered inequality as:

1-2 <= x <1+2

Subtracting 1 from all the sides:

-2 <= x-1 <= 2

This is written as:

|x-1| <= 2 (it is because [tex]|x| \leq a \leftrightarrow-a \leq x \leq a[/tex] )

Thus, an absolute value inequality that has a solution set -1<=x<=3 is |x-1| <= 2

Step-by-step explanation:

The measure of two exterior angles from the given figure are 60° and 90°.

An exterior angle is an angle which is formed by one of the sides of any closed shape structure such as polygon and the extension of its adjacent side. The sum of the measures of the exterior angles of a polygon is equal to 360 degrees, irrespective of the number of sides in the polygons.

From the given figure, the exterior angles are 70°, 2x°, 65°, 75° and 3x°.

Here, 70°+2x°+65°+75°+3x°=360°

210°+5x°=360°

5x°=150°

x=30°

So, 2x=60° and 3x=90°

Therefore, the measure of two exterior angles are 60° and 90°.

Answer:

B and C

Step-by-step explanation:

Kitten:

2 times in the morning and 2 times in the evening = 4 times per day

That means Ariane feeds her kitten 4k grams of food per day.

Dog:

1 time in the morning and 1 time in the evening = 2 times per day

That means Ariane feeds her dog 2d grams of food per day.

Answer:

If you find the total, you have to add the kitten's food per day and the dog's food per day. That is 4k + 2d, which is the same as choice B.

We can break 4k into 2k + 2k. We can also break 2d into d + d. We can write that as 2k + 2k + d + d. That equals the same as choice C, making it a correct choice.

Answer:

16 players can be brought to the tournament. The equation is written within my step-by-step explanation.

Step-by-step explanation:

Variable p = number of players

Set up an equation:

974.50 + 60.75p = 1946.50

Isolate variable p:

60.75p = 972

Divide:

p = 16

Check your work:

974.50 + 60.75(16) = 1946.50

974.50 + 972 = 1946.50

1946.50 = 1946.50
