Answer:
x = 4
Step-by-step explanation:
12/15=28/a which is a=35
then 35+28=63
14x+7=63 and x would be 4
Because 3 is a number and the x is unknow so its just an exponent the x ^ 3 grows three each time
You really just have to do 12.4 x 2 = 24.8 because half of 24.8 is 12.4.
The second graph I believe if not some else will try to help.
