Answer:

y=10

Step-by-step explanation:

$\frac{4}{100}$ = $\frac{y}{250}$

cross-multiply, 4*250=100y

isolate the variable and solve for y, 1000=100y

divide 100 on both sides, 10=y

Square A has a side length of (2x - 7) and Square B has a side length (-4x + 18). How much bigger is the perimeter of Square B t

stich3 [128]

Answer: 100 - 24x

Step-by-step explanation:

The formula for calculating the perimeter of a square is given by :

P = 4l , where l is the length of the side.

Perimeter of square A will be

P = 4 ( 2x - 7 )

P = 8x - 28

Perimeter of square B will be ;

P = 4 ( -4x + 18 )

P = - 16x + 72

Perimeter of square B - Perimeter of square A implies

-16x + 72 - ( 8x - 28 )

-16x + 72 - 8x + 28

collecting the like terms

-16x - 8x + 72 + 28

-24x + 100

⇒ 100 - 24x

Match the width with the given area and length of a rectangle.

torisob [31]

Answer:

5 cm A = 44cm; w = 8.8 cm

7.5 cm A = 48.75 cm2; w = 6.5 cm

5 cm A = 31.25; w = 6.25

9.25 cm A = 55.5 cm; w = 6 cm

Step-by-step explanation:

What you have to do to find the answer is to take the length which for the first problem is 5 cm and then multiply the 5 by each width until you get the area. Example; Length x Width = Area

Basically you use the length times all of the widths until you match up the area.

Hope I could help
