y = number of days
35.50 + 18.25 y = 163.25
18.25 y = 163.25 - 35.50
18.25y = 127.75
y = 127.75 / 18.25
y = 7
so Martin has hired the machine for 8 days
( first day paid 35.50), then 7 days for 18.25
~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:
On the right side of the = multiply -4 through
add 28a and add 4 to both sides
divide both sides by 22
The probability of not drawing C in neither draw is P = 0.5
<h3>
How to get the probability?</h3>
All the cards have the same probability of being drawn, in this case, our set of cards is {F, D, C, G}
The probability of not drawing C is equal to the probability of drawing F, D or G. So we have 3 options out of 4, then the probability is:
p = 3/4.
Now we draw another, this time there are 3 cards, one of these is C, and the other two cards are not C. Then the probability of not drawing C again is equal to 2 over 3.
q = 2/3.
The joint probability (for both of these events to happen) is equal to the product of the individual probabilities:
P = p*q = (3/4)*(2/3) = 0.5
