Answer:
y= -7x+7
Step-by-step explanation:
y= mx+b
y= slope x+ y intercept
Subtract $145-$53 and you will get 92.
Then divide 92 by 23 and you get 4.
The answer is 4 because when you subract 53 from 145 you are seeing how much you paid without the fee.
So take 112 and multiply it by 7, 7x112 = 784.
Answer: A. 3 red squares to 6 green squares
Step-by-step explanation:
Method 1) Find a common factor between 15 and 30. For this problem, I'll pick 5. Divide both numbers by this common factor.
15/5=3 red squares
30/5=6 green squares
<em>3 red squares to 6 green squares</em>
Method 2) Find the greatest common factor between 15 and 30. The GCF is 15. Divide both numbers by the GCF.
15/15=1
30/15=2
This leaves you with a ratio of 1 red square to 2 green squares. 1:2 is equivalent to 3:6
<em>3 red squares to 6 green squares</em>
