8 0

If we call the unknown number x, we have:

  • 7 times a certain number is 7x
  • If we subtract 8, we have 7x-8

If this equals 34, we have

7x-8=34

Add 8 to both sides:

7x=42

Divide both sides by 7:

x=6

andrezito [222]
The ratio is 4:5 meaning out of 9 students 4 are girls and 5 are boys.  If there are 36 students, 9 will go into 36 four times so if we multiply each number of the ratio by 4 it gives us the answer.

4:5
4x4 = 16
5x4 = 20

The ratio is 16:20

16 girls to 20 boys... 16 +20 = 36
