Step-by-step explanation:
divide 60 by 3 cause 3 quarters of an hour is 3/4 then you wanna take half an hour and add that (30 mins) getting 50 minutes
X=4
You have to distribute the negative sign for everything in the parentheses. After that you add x to the other side then add 8 to the opposite side to move them. Then your answer is 4.
Just take each number in the first table and divide it by the total then x by 100
Eg the first one 24/120 x 100 = 20%
