Grant got 21 questions on his test correct and received a score of 84%. How many questions were on the test

25

Step-by-step explanation:

Simplify 84/100 to get to 21/(?). To get to 21 you'd divide 84 by 4 so you'd have to do the same thing to the denominator. 100 divided by 4 is 25, therefore there were 25 questions.

4+n=5

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.
