X= 32.5
You have to change the denominators (8 and 52) to be the same (52).
52/8=6.5
So 6.5 is your scale factor.
Simply multiply your numerator (5) by 6.5 to get 32.6
8+9+10 = 27
27/3 = 9
4+5+6 = 15
15/3 = 5
This is always so, because the third number has one extra that can be added to the first to make them 3x the same numbers.
13. The answer would be B
14. The answer would be C
Answer:
set middle number=x
then left side number=x-1
and right side number=x+1
(x-1)+x+(x+1)＝30
3x=30
x=10
x-1=9
x+1=11
numbers are 9,10,11
