Your answer is D because $25 is a fixed one-time cost, and then you pay $4 every time you visit (x is the amount of times you visit). Your monthly total is $53, and 25 + 4x = 53 sums it up exactly.

How do I know if l -27 l in is less or greater than -45 ​
kondor19780726 [428]

Answer:

If those two line on the side of -27 are there purposefully then they mean absolute value and so that would be positive 27 and on a number line the numbers to the right are greater than the ones on the left

So |-27| is GREATER than -45

The length of a rectangle is 8 feet more than its width. If the width is increased by 4 feet and the length is decreased by 5 fe
alexgriva [62]
Let the width be x.

Length is 8 feet more than width. Length = x + 8

Area = x(x + 8)

width increased by 4, that is,  (x + 4)
Length decreased by 5,    (x + 8 - 5) = (x + 3)

Area  = (x + 4)(x +3)

Area remains the same

x(x + 8) = (x+4)(x +3)

x² + 8x =   x(x +3) + 4(x +3)

 x² + 8x =   x² +3x + 4x +12

x² + 8x =   x² +7x +12        Eliminate x² from both sides

8x = 7x + 12

8x - 7x = 12

x = 12

Dimensions of original rectangle :  x,  x + 8

12, 12 +8 =   12, 20

Original rectangle is   20 feet   by 12 feet
