4 0

Answer:

The width is 19 units. The length is 21 units.

Step-by-step explanation:

W=width: L=length=W+2; P=perimeter=80

P=2(L+W)

80=2(W+2+W)

40=2W+2

38=2W

19=W answer 1: The width is 19 units.

L=W+2=21 ANSWER 2: The length is 21 units.

CHECK:

P=2(L+W)

80=2(21+19)

80=2(40)

80=80

Marcus and his family are planning a vacation that involves horseback riding. Horseshoe ranch charges a $12.95 ranch entrance fe
mart [117]

The equation that models the scenario is y = 12.95 + 14.95x

<h3>How to determine the linear equation?</h3>

The given parameters are:

Ranch charge = $12.95

Entrance fee = $14.95 per house

Represent the number of houses with x, and the total charge with y

So, we have:

y = Ranch charge + Entrance fee * x

This gives

y = 12.95 + 14.95x

Hence, the equation that models the scenario is y = 12.95 + 14.95x
