13. The perimeter P (in yards) of a soccer field is represented by the formula P = 24 + 2w,

rjkz [21]

Answer:

$w = \frac{1}{2}(P - 24)$

$w = 153\ yards$

Step-by-step explanation:

Given

$P = 24 + 2w$

Require

Solving (a):

$P = 24 + 2w$

Subtract 24 from both sides

$P-24 = 24-24 + 2w$

$P-24 = 2w$

Divide both sides by 2

$\frac{1}{2}(P - 24) = \frac{2w}{2}$

$\frac{1}{2}(P - 24) = w$

$w = \frac{1}{2}(P - 24)$

Solving (b):

Substitute 330 for P un the expression in (1)

$w = \frac{1}{2}(330 - 24)$

Evaluate the bracket

$w = \frac{1}{2}(306)$

$w = 153\ yards$
