8 seconds
Step-by-step explanation:
2 1/2 ÷ 2 1/2=1
1*1=1
1*8=8
Put 4:3 into a fraction like 4/3 and make it equal to the number of boys
4/3=216/x
(find x by cross multiplying)
x=162 girls
The parent function is f(x) = x^3
The domain are all x values (-infinity, infinity)
The range are all y values (-infinity, infinity)
Multiply it out, 6v+ 6*4 = final answer. 6v+24

Answer:
8 gallons
Step-by-step explanation:
The $2 difference in the price of a car wash is made up by the gas purchase at the rate of $0.25 per gallon. So, it takes ...
$2/($0.25/gal) = 8 gal
to make the costs the same.
The customer must purchase 8 gallons for the total cost to be the same at both gas stations.
___
3.50g +8 = 3.25g +10 . . . . costs at each station for g gallons of gas + wash
0.25g = 2 . . . . . . . . . subtract 3.25g+8 from both sides
g = 2/.25 = 8 . . . . . . the way we did it above
