Answer:
x= 15/4
Step-by-step explanation:
Starting Equation
(x/3) - (1/2) = 3/4
Add 1/2 by both sides
(x/3) = 3/4 + 1/2
Find the common denominator (4)
(x/3) = 3/4 + 2/4
Add
(x/3) = 5/4
Multiply 3 by both sides to get x by itself
x = 15/4
30% of 70 is simply 0.3 * 70, which equals to 21
The solution to x + 8.5 = 64.5 is 56.
x + 8.5 = 64.5
- 8.5 - 8.5
---------------------------
x = 56
The answer is D because the y is the only thing that is changing.
