Let the number of gallons consumed be the first car be x, and that of the second car, y. Then:
x + y = 50 . . . . . . . (1)
20x + 15y = 850. . . (2)
(1) x 20 => 20x + 20y = 1000 . . . (3)
(2) - (3) => -5y = -150 => y = -150/-5 = 30
From (1), x + 30 = 50 => x = 50 - 30 = 20
Therefore, first car consumed 20 gallons and the second consumed 30 gallons.
First, make it into slope intercept form. Subtract x form both sides
x (-x) - y = 5 (-x)
-y = -x + 5
Isolate the y. Divide -1 from both sides
(-y)/-1 = (-x + 5)/-1
y = x - 5
The slope in the form: y = mx + b, is m, which is next to the x
In this case, the m is 1
You're slope is 1
hope this helps

Answer: If the radio boys to girls is 2:3 you can solve the problem with equivalent fractions: 2/3 = 8/x , to be equivalent you have to multiply the numerator and denominator by the same number, which for this case has to be 4. The answer is: if there are 8 boys , there are 12 girls
