Question

Please help me solve numbers 7 & 9. Thanks. Will mark Brainliest!

Answer 1

So to solve for a variable, you just need to isolate the variable onto one side. In this case, isolate a onto one side to solve for it.

7.

Firstly, multiply both sides by a: $au=k$

Next, divide both sides by u, and your answer will be $a=\frac{k}{u}$

9.

For this, just divide both sides by 12m, and your answer will be $a=\frac{4}{12m}=\frac{1}{3m}$
