Answer:
64
Step-by-step explanation:
First, you divide 416 by 65. This gets you 6.4. But it's not 1 in 65 eating pizza, it's 10 out of 65, so then you multiply 6.4 by 10, getting 64.
1/5 of 152 is 30.4
1/2 of 152 is 76
1/4 of 152 is 38
hope this helped :)
Answer:
21°
Step-by-step explanation:
set it up
7x-1+3x-9=180
combine like terms
10x-10=180
take the ten to the other side
10x=190
divide both sides by 10
x=19
plug x in
3(10)-9
30-9
21
(Incase you need it the other angle is 159°)
Lets say your numbers are these...
10,20,30,40,50,60,70,80,90 and 100
you would add those to get 650
Now how many numbers did you add?
You added 10
so now divided
650 by 10
you get 65
that is the mean of those numbers!
