~Hello There!~

\frac{m}{s} =\frac{2}{5}

Rearrange for s

s = \frac{5m}{2}

After 8 years, the new equation would be:

\frac{m+8}{s+8} =\frac{1}{2}

Cross multiply

2m+16 = s+8

Subtract 8

2m+8=s

Substitute old equation

2m+8 = \frac{5m}{2}

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 ^_^

The class needed to collect 20.5 pounds of cans for recycling over the next 5 months. the students plan to collect 3.75 pounds e
Anestetic [448]
To solve this problem, start by finding how many cans will be collected in 5 months. To do this, take the amount of cans collected each month and multiply it by the number of months. Set these values up in an equation.
This leaves you with:
3.75(5) = x

Multiply the values to get 18.75 pounds of cans.
So this fills the first blank.

For the second blank, you must subtract the number collected from the number that was the goal for the class.
This results in the expression:
20.5 - 18.75

Subtract the values to fill the second blank with 1.75 pounds.

Since they didn’t meet their goal, the last blank would be “less.”

I hope this helps! :)
