Question

I'd also appreciate if someone would help me out with this, thank you

Answer 1

C = 42

Explanation:

½ c + 45 = 66

½ c + 45 − 45 = 66 − 45

2 × (½ c) = 2 × 21

C = 42

Answer 2

c=42

Explanation:

First you would find out how much you would add to 45 to give you 66. Which is 21. Then you double it, so when you put it over the two it looks like this 42/2. So when you reduce the fraction you get 21. Hence 21+45=66.

Hope this helps!
