Answer:
7 = 2 + r
Step-by-step explanation:
So since we know the hanger is <em>balanced</em>, we can determine that r = the amt. of the other side - 2. =>
We can count the amt. of "1" on the side of the hanger with only 1 --> to get 7 "1" which is 7(1) = 7.
The other side with "r" has 2 "1" thus --> 2(1) = 2
So, 7 = 2 + r is our equation and if we were to solve for r, => r = 5
