Question

were on his Algebra test?
HELP PLEASE✨

Answer 1

29 questions on his test

Explanation:

set it up as fractions equal to each other so that you can solve for x

`76\%= (76)/(100)`

x is the total number of questions on the test

we know that samuel got 22 of those questions correct, and a grade is calculated by dividing the number of correct answers by the total number of questions, so we can write

`(76)/(100)=(22)/(x)`

then you can solve by cross multiplying

`76x = 22 (100)`

`76x=2200`

get the x by itself by dividing both sides by 76, and then you have x

`(76x)/(76)=(2200)/(76)`

`x=(2200)/(76)=28.947`

since you're not going to have .947 of a question, round it up to 29

and then you have it

`x=29`
