With percentage in the question, you divide the miles they drove by the total miles in the trip (and of course multiply it by 100).
Joe:

.3077 times 100= 31% (just rounded the percentage to the nearest whole number).
Adam:

.5385 times 100= 54%
Laura:

.1538 times 100= 15%

Answer:
A
Step-by-step explanation:
Given
x² = 16 ( take the square root of both sides )
= ±
← note plus or minus sign
x = ± 4
Since 4² = 4 × 4 = 16 and
(- 4)² = - 4 × - 4 = 16
<span>We simplify the equation to the form, which is simple to understand
<span>7x-1/2(8x+4)=6
</span></span><span>Simplifying:
<span>7x-0.5*(8x+4)=6
</span></span><span>Reorder the terms
<span>7x+(-4x-2)=6
</span></span><span>Remove unnecessary parentheses
<span>+7x-4x-2=+6
</span></span><span>We move all terms containing x to the left and all other terms to the right.
<span>+7x-4x=+6+2
We simplify left and right side of the equation.
<span>+3x=+8
We divide both sides of the equation by 3 to get x.
<span>x=2.66666666667</span></span></span></span>
Answer:
-15x + 39 = -3(5x - 13)
Step-by-step explanation:
a. -3(5x - 13) = -15x + 39
b. -3(5x + 13) = -15x - 39
c. 3(5x - 13) = 15x - 39
d. 3(5x + 13) = 15x + 39
