Number of red cars = x
Number of white cars = y
x + y = 75
y + 3 = 2x
x + y = 75
y = 75 - x
(75 - x) + 3 = 2x
78 = 3x
26 = x
y + 3 = 2(26)
y + 3 = 52
y = 49
There are 49 white cars.
Solve for x, which can be done by moving x to the other side.
2(x-5)^2+8
So, x = 5
The y value is the number at the end and we can see that it is positive 8.
y = 8
Write it out as a coordinate pair and you would get (5,8) or answer choice D
I believe the answer to that problem would be $68.55, since you have to add them together and then multiply them by .07 for the percentage.
Answer:
84.4 gallons to the nearest tenth.
Step-by-step explanation:
Average usage = miles travelled / gallons used so:
6.3 = 532 / gallons used
Gallons used = 532 / 6.3
= 84.44.
