Pretty fast consider 115ft wasn't enough to avoid an accident..
We want to know how much is the price per pound (or unit rate) of ground beef, given that we know the price for Elliot's purchase. We will see that each pound costs $4.75
So we know that (3 + 2/5) lb of ground beef costs $16.15, the cost of a single pound will be given by the quotient between the total cost and the amount purchased, then we need to solve:

We can rewrite the denominator as:
(3 + 2/5)lb = (15/5 + 2/5)lb = (17/5) lb
Replacing that we get:

So each pound of ground beef costs $4.75

Here is your answer:
Move all terms with m to the left, all other terms to the right:
m + 2n + -2n = -2n + p
Combine like terms:
2n + -2n = 0
m + 0 = -2n + p
Which would equal "m = -2n + p" after you simplify.
Hope this helps!

Answer:
x = 20 degrees
Explanation:
With a 20 degree angle on the direct opposite side, it shows that x is also 20 degrees; and the other two angles would be 160 degrees.
