Final answer:
The student made errors in solving the equation 1/4r + 2 = 10. The correct steps include subtracting 2 from both sides to get 1/4r = 8, then multiplying by 4 to find r = 32.
Step-by-step explanation:
The student appears to have made an error in their steps for solving an equation. Let's clarify the correct steps:
- Starting with the equation 1/4r + 2 = 10, subtract 2 from both sides to isolate the term with the variable r.
- You then have 1/4r = 8, not 12 as listed in step B.
- Multiply both sides by 4 to solve for r, giving you r = 32, not 48 as in step C.
So, the correct steps are subtracting 2 from both sides and then multiplying by 4, which gives you the solution r = 32.
It looks like there was a misunderstanding with the numbers and operations used to solve the equation. When dealing with such problems, it's important to carefully follow algebraic rules and check each step for accuracy.
