You use a system of equations
x= coffee
y= donuts
x+y=100
3x+y=180
there’s 3 ways to solve system of equations substitution graphing and elimination. it would be easiest to use substitution here. So you multiply x+y=100 by -1 so it become -x-y=-100. then you combine it with the other equation and get 2x=80 so x=40 which means 40 cups of coffee were sold then you plug it back in to find y. 40+y=100. y=60.
y= 60 (donuts). x= 40 (coffee)
Answer:

Answer:
x = 1.2
Step-by-step explanation:
Essentially, because ABCDE and JKLMN are similar, their corresponding sides have a common ratio. To find x, we can simply the ratio between NJ and its corresponding side equal to the ratio of another pair of corresponding sides.
3x = 3.6
x = 1.2
T-T this took waaaaaay too long to be helpful but I hope it is anyways!
