-2x + 6y = 6
6y - 6 = 2x
6(y-1) = 2x
(1/2) * 6(y-1) = 2x * (1/2)
x = 3(y-1)
------------
If, x = 3(y-1),
-7 * 3(y-1) + 8y = -5
-21 * (y-1) + 8y = -5
-21y + 21 + 8y = -5
21 + 5 = 21y - 8y
26 = 13y
y = 26/13
Therefore: y=2.
----------
If y=2,
x = 3(2-1) = 3

Answers:
x=3 and y=2.
For every 6 apple pie, you need 2 pounds of apples.
So, how many pounds of apples do you need for 10 apple pies?
Well, first to figure out this question we first need to make a conversion factor.
I see in the fraction 6/3 we can simplify that to 2/1. Now we got our conversion factor.
We need to invert the fraction in order for the pie unit to cancel out.
1/2 * 10 = 5
You will need 5 pounds of apples to make 10 apple pies.
Answer:
a. 1.25 laps per min
b. .8 min per lap
c. 17.6 minutes

Step-by-step explanation:
b.
The sum of two opposite interior angles equals one exterior angle
111°=60°+‹G
‹G=111°-60°=51°
c.
We use the same property above
3x+4x+5=68°
7x=68-5
7x=63
x=63/7=9
‹D=4(9)+5
‹D=41°
