For every 4 mangos teens that Ben gets, David gets 5. If David gets 30 mangos teens, how many mangos teens do they get altogether?

46

Step-by-step explanation:

because if David got 6 times of 5

then ben got 6 times of 4 which is 16

now add 30 and 16 the answer will be 46

$15 each

step-by-step explanation:

$45/3 children= $15 each

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
