Answer:
Solve the 1st equation for y and then you substitute the answer of the y value to the other equation to get the x value
Answer:
y=mx+b
3=slope
1=y coordinate
-8=x coordinate
b=y intercept
Substitute m for 3
y=3x+b
Next, substitute the coordinate values
1=3(-8)+b
Solve
1=-24+b
+24 +24
25=b
Now substitute b and m for their respective values
y=3x+25

Answer:
<h2>
0.67</h2>
Step-by-step explanation:

Distribute 5 through the parentheses

Distribute 4.7 through the parentheses

Move ' 4.7 y ' to L.H.S and change it's sign

Move constant to R.H.S and change it's sign

Collect like terms

Calculate

Divide both sides of the equation by 0.3

Calculate

First you find the unit rate. (Divide 2.76 by 18)
You will find out that each ounce costs $0.15
Then divide 2.07 by 0.15.
The answer is 13.8 ounces.
