Answer:
330
Step-by-step explanation:
I don't know what it wants you to use, you can see intuitively that you must multiply the 22 by a multiple of 5
22 x 5 = 110
110 / 15 = 7.3
22 x 10 = 220
220 / 15 = 14.6
22 x 15 = 330
330 / 15 = 22
Answer:
x=-1
Step-by-step explanation:
You can set up an inequality to solve this. You can either do big to small --> 
or small to big --> 
. I'm going to be using big to small because I think it's a little easier.
Cross multiply and you will get:
Isolate x:
x = 
x = 45
