56 is your answer.
Equation for direct proportion is y = kx where k is the constant of proportionality. For your letters, it’s f = ka
We know 72 =k9, so k = 8
Then they want you to solve
f = 8•7
f = 56
Steps to solve:
4 - 3x = 2(x - 3)
~Distribute
4 - 3x = (2 * x) + (2 * -3)
~Simplify
4 - 3x = 2x - 6
~Subtract 4 to both sides
4 - 4 - 3x = 2x - 6 - 4
~Simplify
-3x = 2x - 10
~Subtract 2x to both sides
-3x - 2x = 2x - 2x - 10
~Siimplfy
-5x = -10
~Divide -5 to both sides
-5x/-5 = -10/-5
~Simplify
x = 2
Best of Luck!
1.60 *3 is 4.80-1.95=2. 85 a large container is $2.85
The answer should be x=8 if you are looking for what x is
