Simplifying 0.20 = x^2 / (25 - x):
Multiply both sides by (25 - x)
0.20(25 - x) = x^2
Distributing 0.20:
5 - 0.20x = x^2
Placing all equations on to one side:
x^2 + 0.20x - 5 = 0
Where:
a = 1
b = 0.20
c = -5
6 = 3(x - 2)
6 = 3x - 6
3x = 12, x = 4
Solution: D
The answer is 35 pounds because,
56 / 8=7 so 5x 7 =35 pounds
You have to take the x to on side and numbers to the other but in order to do that you'll have to divide -3 from both sides and then just solve the equation.
