60% of the students in mrs armstrong's class returned to their field trip permission slips. if mrs armstrong collected 21 permission slips, how many students are in the class ?

the correct answer is x/3+10≥32

hope this !

i think the answer is a p = 78

step-by-step explanation:

there are 6 sides of a hexagon, multiply 13 x 6

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!

that would be a prism, if not right, feel free to correct me
