15x+40=115
15x means 15 per week solve for x if you want to know how many weeks 40 is what he has only once
1) find x
y=1/(x+3) -4
y+4=1/(x+3) -4+4
y+4=1/(x+3)
x+3 =1/(y+4)
x= 1/(y+4) - 3
2) change x on y , and y on x
x= 1/(y+4) - 3
y= 1/(x+4) - 3 This is an answer.

Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.
To simplify the ratio. You have to find both of these numbers Greatest common factor. Which happens to be 3 :P
So divide each number by 3
15 ÷ 3 = 5
---------------
3 ÷ 3 = 1
So this means our new simplified ratio is...
5 seconds to 1 minute.
Good Luck! :)
