3:
in biology class, the girl to boy ratio is 3 to 10. if there are a total of 52 students, how many boys are there?

40 boys

Step-by-step explanation:

the ratio at first is 3 girls to 10 boys so you can use multiplication and addition to figure this out.

3 times 4 equals 12

10 x 4 = 40

whatever you multiply on one ratio you do to the other ratio. 40 + 12 = 52

Now the question is asking how many BOYS are there.

there are 40 boys.

answer: 2530

hope this

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
