The length of a rectangle is 7/6 its width, w. Which expression represents the perimeter of the rectangle?

Hitman42 [59]

If the length is 7/6 the width w then the perimeter is w + (7/6)w + w + (7/6w)
= 2((7/6)w + w) = 2w + (14/6)w = (26/6)w = (13/3)w.
So the answer is the last one.

MANUFACTURING A shoe manufacturer spends $2.50 to make sandals and $4 to make running shoes. During a typical month, they spend

jonny [76]

Answer:

200 pairs of sandals

Step-by-step explanation:

Represent the sandals with x and the running shoes with y.

In a typical month:

$Total = 2500$

In April

$Total = 3000$

Required

The number of sandals in a typical month

In a typical month:

If 1 sandal costs 2.50, then x costs 2.50x

If 1 running shoe costs 4, then y costs 4y

The total is:

$2.50x + 4y = 2500$

In April:

If 1 sandal costs 2.50, then 2x costs 5x ---- we used 2x because the pairs is doubled

If 1 running shoe costs 4, then y costs 4y

The total is:

$5x + 4y = 3000$

The equations are:

$5x + 4y = 3000$

$2.50x + 4y = 2500$

Subtract

$5x - 2.50x + 4y - 4y = 3000 - 2500$

$2.50x = 500$

$x = \frac{500}{2.50}$

$x = 200$
