3/5 = 72/x
First u need to cross multiply
5*72 = 360
Now divide
360/3 =120. <<< that's x
So
3/5 = 72/120 < answer
Answer:
10x + 15y = 450
Step-by-step explanation:
A store sells bracelets for $10 and rings for $15.
Sold 30 items.
They counted the money they made $450.
x = bracelets
y = rings
10x + 15y = 450
No options shown, but any line where x = -2y
For instance: y = -1 and x = 2
Remember slope is rise-over-run
y is rise, x is run
