To solve the equation \( \frac{5}{8}(x + \frac{1}{2}) = 100 \), we can follow these steps:
Step 1:
First, eliminate the fraction by multiplying both sides by 8: \[ 5(x + \frac{1}{2}) = 800 \]
Step 2:
Next, divide both sides by 5: \[ x + \frac{1}{2} = 160 \]
Step 3:
Subtract \(\frac{1}{2}\) from both sides to isolate \(x\): \[ x = 160 - \frac{1}{2} = 159.5 \]
Thus, putting the responses in order would be:
- Multiply both sides by 8 to eliminate the fraction.
- Divide both sides by 5.
- Subtract \(\frac{1}{2}\) from both sides to solve for \(x\).
Now, for the second equation \( \frac{5}{8}(x + 12) = 100 \):
Following similar steps:
Step 1:
Multiply both sides by 8: \[ 5(x + 12) = 800 \]
Step 2:
Divide both sides by 5: \[ x + 12 = 160 \]
Step 3:
Subtract 12 from both sides to isolate \(x\): \[ x = 160 - 12 = 148 \]
So, the correct answer to this equation is \(148\).
If you are given multiple-choice options for \(x\) in the second question, please refer to those and match with the calculated value.
