Answer:
Same side interior angles
They are also supplementary (add up to 180 deg)
Step-by-step explanation:
see attached
7x+3y=25
-2x-y=-8
7x+3y=25
(-2x-y=-8)3
7x+3y=25
-6x-3y=-24
x. =1
x=1
now you plug in that x value
-2(1)-y=-8
-2-y=-8
+2. +2
-y = -6
-1. -1
y = 6
(1,6)
The answer to this really simple question is 6
Answer:
6 pairs
Step-by-step explanation:
It is given
3.5 lbs = 4 pair
We want to know:
5.25 lb = HOW MANY PAIR? (let this be x)
Now, we can write two ratios and equate them, cross multiply and find x(the pair of shoes that can be made with 5.25 pounds of leather). The ratios and algebra is shown below:

Thus,
with 5.25 lbs of leather, 6 pairs can be made
