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
