Answer:
-11
Step-by-step explanation:
A=12
120% of a =80% of b
120%a = 80%b
120a/100 = 80b/100
Divide through by 100
120a = 80b
Divide through by 80
120a/80 = b
But a=12
120x 12/80 = b
18 = b
b = 18
a+b = 12 + 18 = 30
Answer:
Its what you have to figure out
Step-by-step explanation:
Answer: 2 3/4
Step-by-step explanation: 1/4 + 3/4 is 1 whole plus 1/4+1/4 would equal the 1/2 you need.
So we are up to 3/4 already. 1 3/4 + 3/4 = 2 1/2
We need to add 2 more to get to 4 1/2
So the answer would be 2 3/4
2 3/4 + 1 3/4 = 4 1/2
