Answer:
8
Step-by-step explanation:
yellow marbles=2b-7
blue marbles=2b
2b+2b-7=23
4b=23+7
4b=30
b=30/4
b=7.5
yellow marbles=2b- 7
2 x 7.5 -7
15 - 7
=8
Answer:
Step-by-step explanation:
32/40=22 you do the math
So dad=28
cindy=2
so 28-2=diffirance in age=26
A. dad-26=cindy
cindy=dad-26
dad=cindy+26
so since cindy=18
dad=18+26=44
B. if dad =42=cindy+26 so
42=x+26
subtract 26 from both sides
16=x
cindy =16 if dad =42
C. so the number of years apart they will be will always be 26 (until one of them dies)
X=1/6? Not too sure though
