You have 33 math and seicne problems. for homework you have 7 more math prblems than science problems. how many problems do you have in each subject?

Math Problems: 20

Science Problems: 13

Step-by-step explanation:

First define your variables.

Let m = # of math problems

Let s = # of science problems

m + s = 33   <-- Because there are 33 total problems

m = s + 7   <-- Because there are 7 more math problems

Solve by substitution method, replace m in the first equation with s + 7

s + 7 + s = 33  

2s + 7 = 33  <-- Combine like terms

    - 7     -7

     2s = 26

       s = 13  <-- Divide by 2

We now have s, so we can plug it back into an original equation to find m

m = s + 7  =>  m = 13 + 7 =>  m = 20

So,

Math Problems: 20

Science Problems: 13

To confirm, we note that 20 + 13 = 33 so both equations are satisfied.

Good luck

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
