We want to find the amount of books each 6th grader would need to read, so we would use division for this problem:
3072 books / 96 sixth-graders
3072/96=32
Each 6th grader would have to read 32 books.
Yes that is right so you just plug in the days as x then multiply the new x with the number to the left of it then add the number on the right and finally that is your y
(180-x)-2(90-x)= 53
Remember that complimentary angles add to 90 and supplementary angles add to 180.
180-x-180+2x=53
x=53
Final answer: The angle is 53 degrees.
What is your question...?
