Answer:
x=9
Step-by-step explanation:
subtract 22 from both sides, simplify 3x = 10x-63, subtract 10x from both sides of the equation, simplify -7x = -63, divide both sides of the equation by the same factor -7x/-7 = -63/-7, then simplify
I believe that the answer is C, I don't know if it is addition or multiplication, but if is is addition, it would be 146, C
What are the choices. I need them in order to answer with the best/correct answer.
The first square is 100% and the second square is 55% filled in
This is the concept of algebra,
The fraction of children was: 3/8
fraction of adults was 1-3/8=5/8
fraction of men 3/4*5/8=15/32
fraction of women=5/8-15/32=5/32
Given that there was 140 more children than men, the fraction representing this will be:
(3/8-5/32)
=7/32
thus the total number of people will be:
1/(7/32)*140
=32/7*140
=640
the total number of people was 640
