Question

Idk how to do this, I need the work and answer please.

Answer 1

one way you can solve this is with a proportion it is set up like this

`(10 )/(5) = ( x)/(7)`
on the top you have the test and the x represents the test we are trying to find. on the bottom is the number of weeks that you've taken. first you will have to do 5 times x. and then 10 times seven then you will end up with a set up like this

`5x = 70`
next you will divide both sides by 5. ( you always divid by x) and what you do on one side you have to do on the other. 5x divided by 5 is x and 70 divided 5 is 14. so your answer will be

`x = 14`
I hope you understand

Answer 2

I think it is 14
because 10÷5=2 which means 2 test per week and 2×7=14
