If you simplify 35/10 both side divide by 7 is equal to 7/5
You could set up a ratio:

which then becomes:
The answer is 168. 12% is also 0.12. 150(0.12) is 18. 150+18=168
Our goal is to get y by itself
We will first add 3x to both sides to get
-5y = 3x - 15
We will then divide both sides by -5 to get y by itself which becomes
y = -3/5x + 3
Answer: Students 1 and 3
Step-by-step explanation:
student 1=
- (5r+3s-1)=
-5r+3s-1=
the same answer as student 3
