Answer: The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.
Step-by-step explanation:
The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.
Your doing the Distributive Property. So in this equation your distributing the first 2 on the outside of the parenthesis, so this first section of your problem after distributing is 6n+8. Next distribute the -2 to the 2n and 5. DON'T FORGET THE NEGATIVE. So it would look like 6n+8-4n-10. Then combine like-terms. so 6n-4n = 2n. Then 8-10=-2. Your final answer should be
2n-2.
Hope this helped.
4(y - 1) - 1 = 2(2y - 3)
4(y) - 4(1) - 1 = 2(2y) - 2(3)
4y - 4 - 1 = 4y - 6
4y - 5 = 4y - 6
- 4y - 4y
-5 ≠ -6
Answer:
51ft, 17ft, 39ft
Step-by-step explanation:
longest = x
2nd = 
x
3rd = x - 12
P = 107
a + b + c = Perimeter
x + x + x - 12 = 107
x -12 = 107
x = 119
x = 51
x = 17
x - 12 = 39
Answer:
86°
Step-by-step explanation:
(a+c)/2=86
in this case, a=c
so,
2c/2=86
or, c=86
