Answer: 59 & 21
Step-by-step explanation:
so this probably won't be the best explanation, but here goes:
For the sake of knowing the two numbers aren't equal to each other, I decided to do variables n and x, so:
n+x=80
Now we need to find the value of n:
So the question sets this up as
n-2x=17. We need to change the equation so that we're solving for n, so: n=17+2x
Next we need to solve n+x=80, to do that we need to make it into x=80-n
Now that they're set up like this we can do : 80-n=17+2x.
I honestly don't know how to explain it the rest of the way but if you plug in those two numbers they should be right.
The pricing of the boxes seems to be consistently 2.40 per box. Ethan's cost is
.. 52.80 = 2.40 * (# of boxes)
.. 52.80/2.40 = (# of boxes)
.. 22 = # of boxes
Ethan has bought 22 boxes for 52.80.
Answer:

Answer:
Step-by-step explanation:
Use two given points (-6, -3) and (6, -7) to find equation of the line.
<u>The slope:</u>
- m = (y₂ - y₁)/(x₂ - x₁) = (-7 - (-3)) / (6 - (-6)) = -4 / 12 = - 1/3
<u>The y - intercept is also visible on the graph (0, -5): </u>
<u>The line is:</u>
