Answer:
y=2.4
Step-by-step explanation:
9y-2+y=5y+10
(combine like terms)
10y-2=5y+10
(subtract 5y from both sides)
5y-2=10
(add 2 to both sides)
5y=12
(divide both sides by 5)
y=2.4

Answer:
The 3 numbers must be multiples of 3, 4, and 5
Step-by-step explanation:
Pythagorean Triples are numbers that you know will come out perfectly in the Pythagorean Theorem. But the easiest way to explain this is to show you an example.
Say you're given the numbers 12, 16, and 20.
They should be able to be divided by the same number and equal 3, 4, and 5.
In this case, the number is 4.
12/4=3
16/4=4
20/4=5
So, this is a 3-4-5 triangle, or a Pythagorean Triple.
Answer:
n= -11/4 or n= -2 3/4
Step-by-step explanation:
Answer:
x^2 - 5x - 66
Step-by-step explanation:
1. Distrubute the x to the x and -11 so you will get x^2 - 11x
2. Distrubute the 6 to x and -11 and you get 6x - 66
3. Combine like terms (x^2 - 11x + 6x - 66) you will get x^2 - 5x - 66
