The ratio of girls and boys is 3 to 5. If there are 40 kids altogether, how many are boys, and how many are girls?

15 are boys and 25 are girls

Step-by-step explanation:

3:5 is 40

3x+5x=40

8x=40

x=5

5*3 and 5*5

which is 15 and 25

Hope this helps!

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
