The Food-Mart grocery store has a candy machine like the one pictured here. Each time a child inserts a quarter, 7 candies come
out of the machine. The machine holds 15 pounds of candy. Each
pound of candy contains about 180 individual candies.
1.
how many customers will there be before the machine is empty?

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

the barter

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
