D) 7/8

All are right except for 3.

I see my mistake. 42.07-15.99=26.08

74.05-15.99=58.06

x − 15.99 = 58.06

Add 15.99 to both sides.

To solve these equations, we'll go through the steps one by one.

1. Solve the equation 6 - x = -12:
- First, we want to isolate the variable x, so we need to get rid of the 6 on the left side by subtracting it from both sides:
6 - x - 6 = -12 - 6
- x = -18
- Now, we need to solve for x by multiplying both sides by -1 to cancel out the negative sign:
-1 * (-x) = -1 * (-18)
x = 18
- So, the correct answer is D) 18.

2. Solve the equation x + 1.33 = 7.82:
- We want to isolate the variable x, so we need to get rid of the 1.33 on the left side by subtracting it from both sides:
x + 1.33 - 1.33 = 7.82 - 1.33
x = 6.49
- So, the correct answer is A) 6.49.

3. Solve the equation x - 15.99 = 58.06:
- We want to isolate the variable x, so we need to get rid of the -15.99 on the left side by adding it to both sides:
x - 15.99 + 15.99 = 58.06 + 15.99
x = 74.05
- So, the correct answer is C) 42.07.

4. Solve the equation 1.32x = 8.976:
- We want to isolate the variable x, so we need to divide both sides of the equation by 1.32 to cancel out the coefficient of x:
(1.32x) / 1.32 = 8.976 / 1.32
x = 6.8
- So, the correct answer is C) 6.8.

5. Solve the equation x/4 = 3/8:
- We want to isolate the variable x, so we need to multiply both sides of the equation by 4 to cancel out the denominator of x/4:
(x/4) * 4 = (3/8) * 4
x = 3/2
- So, the correct answer is B) 3/2.
