Answer:
1. When he sold 20 slices of pizza at $1.25 each, he made $20
When he sold 50 slices of pizza at $1.25 each, he made $62.5
2. 96 slices of pizza. You would get that by dividing 120 by 1.25, as he needs to make $120, and each slice costs $1.25
Answer:
2.8 years or 33.6 months.
Step-by-step explanation:
I am not sure what your questions is, but I assume it is how long it will take to pay it off?
In a year (15*12,) you would have paid $180 of it.
x = 500/180
Therefore, it will take you approximately 2.8 years to pay off your loan, excluding interest, of course, since you did not provide that rate.
You should add -77 to 77 because it will cancel out.
Right triangles must follow the pythagorean theorem, so a^2+b^2=c^2.
Let's find a^2 and b^2 by squaring the first 2 side lengths.
(x^2-1)^2= x^4-2x^2+1
(2x)^2= 4x^2
Then add the two to find c^2
x^4+ 2x^2 +1= c^2
Root both sides
x^2+1=c
Since the side lengths can be plugged into the pythagorean theorem, the side lengths must represent a right triangle.
Hope this helps!
