~Hello There!~
Rearrange for s
After 8 years, the new equation would be:
Cross multiply
Subtract 8
Substitute old equation
Solve to get m as 16.
s = 40.
Their current ages are 16 and 40 and the different is 24 years. Therefore, Caitlin is correct.
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^

Answer:
Step-by-step explanation:
Hello
Which expression is equivalent to 1/3 (5x + 3y) + 2/5y + 7 ?
a. 5/3x + 2/5y + 7
b. 5/3x + 7/5y + 7
c. 15x + 9 2/5y + 7
d. 15x + 2/5y + 7
1/3 (5x + 3y) + 2/5y + 7
= 5/3 x + y + 2/5 y + 7
= 5/3 x + 5/5 y + 2/5 y + 7
= 5/3 x + 7/5 y + 7
Answer : b
