Answer:
There would be 11 gallons of gas left!
Step-by-step explanation:
Answer:
3 (5x+7) = 75
15x + 21 = 75
15x + 21 - 21 = 75 - 21
15x = 54
x = 3.6
Step-by-step explanation:
Answer:
y = 2
Step-by-step explanation:
y varies inversely with x setup is:
y = k/x
7 =
(find 'k')
k = 7/1 · 2/3
k = 14/3
use what you know about 'k' and 'x' to solve for 'y'
y = 14/3 ÷ 7/3 (remember to multiply by the reciprocal when dividing fractions)
y = 14/3 · 3/7
y = 2
2 3/4 that is at least the shortest term
60 miles because if you plug it in, it says she uses 2 gallons of gas. You can substitutes D=30(2), which comes out to 60
