Read each formula and rearrange it to solve for the indicated variable. Show your work.
1. The formula for the area of a rectangle is A = lw. Rearrange the formula to solve for length (l).
2. The formula for simple interest is I = Prt. Rearrange the formula to solve for the principal amount (P).
3. To solve for 'y' in the equation 2x + y = 7, you would from both sides, resulting in y = .
4. In the formula d = rt, where d is distance, r is rate, and t is time, if you want to find the time (t), the rearranged formula would be t = .
5. Which of the following is the correct rearrangement of P = 2l + 2w to solve for 'w'?
w = P - 2l
w = (P - 2l) / 2
w = P / 2 - 2l
w = 2P - l
6. Given the formula F = ma, if you want to solve for 'a', what is the correct rearranged formula?
a = F + m
a = m - F
a = F / m
a = F * m
7. The formula for the circumference of a circle is C = 2πr. Rearrange the formula to solve for the radius (r).
8. The formula for density is D = m/V. Rearrange the formula to solve for volume (V).
