Answer:
9
Step-by-step explanation:
Create a proportion

84 divide by what gives you 12? 7
So divide 63 by 7, and you get 9.
This doesn't work with all of these problems so you can always cross multiply then divide.
12(63) = 756
84(x) = 84x
84x = 756
84x/84 = 756/84
x = 9
Answer:
D. -10, 10
Step-by-step explanation:
Instead of inserting values into x to solve, let's isolate x.
In order to do this, we must take the square root of both sides.


To find the square root of 100, we must figure out what = 100 when multiplied by itself. Reminder, it can be both a positive or a negative square root, as positive times positive is a positive, and negative times negative is a positive.
The square root of 100 is -10 or 10, as 10 x 10 or -10 x -10 = 100.
