At approximately 4.5 hours.
15.75x + 70 = 13.25x + 81
15.75x - 13.25x = 81 - 70
2.5x = 11
x = 4.4
found to the nearest tenth 4.5

We need to find out how much is worth one yard in both fabrics, so we divide $15.00 by 2 and $37.50 by 5:
$15.00 ÷ 2 = $7.50 per yard
$37.50 ÷ 5 = $7.50 per yard
As both prices per yard are the same, the answer is: <span>Yes, these fabrics have the same unit cost.</span>

We know one leg of a right triangle as well as its hypotenuse. We need to find the other leg using the Pythagorean Theorem.
The Pythagorean Theorem states that
, where
and
are the legs and
is the hypotenuse.
Insert the known values into the equation. The distance between Susie's house and the school will be represented by
.

Convert the decimals to fractions.

To raise a fraction to a power, raise both the numerator and the denominator to that power.

Multiply both sides of the equation by
.

Subtract
from both sides.

Subtract.

Divide both sides by
.

Take the square root of both sides.
