Okay, we start with 42x^2 + 32 - 18 = 6062. To solve single-variable equations like this one, we want to isolate the x by moving all of the other numbers to the other side of the equation. We need to first subtract 32 and 18, and that equals 14. Now our problem looks like this, 42x^2 + 14 = 6062. Since 14 is the only other number on the left side, we subtract four from both sides! This gives us 42x^2 + 14 - 14 = 6062 - 14, so 42x^2 = 6062. Now to find x, we want to just have one x on the left side instead of 42, so we divide the equation by 42 to find that 42x^2/42 = 6048/42, so x = 12
Answer:
H
Step-by-step explanation:
there is 10 parts to the shape so your denominator would be 10 then if you count the shaded area there's 8, so 8 would be your numerator
8/10 = 0.8 or 80%
Commision equals percentage times the amount of money bought for the car. It will be 1.5% (0.015) * 22500. The answer is $337.50.
