If the ratio of girls to boys is 3:7,
then: 3/10 of the class are girls and 7/10 of the class is boys
Note: 3+7 = 10
If the class has a total of 50 students we can find the number of boys by doing this:
(total number of kids) x (fraction of the kids that are boys) = # of boys
50 x (7/10) = 35
There are 35 boys in the class.

Answer:
x = 37
Step-by-step explanation: Every angle in a triangle adds up to 180, so we can set up an equation where (x + 48) + (x + 58) = 180. From here, we can combine like terms to get 2x + 106 = 180. 180-106 is 74. 74 divided by 2 is 37. So, x = 37.
