Answer:
A
Step-by-step explanation:
To sovle this we must combine the numbers togther and the variables togther.
We have:
8c+6-3c-2
Lets take out the c's and combine them:
8c -3c
=
5c
Now lets take out the numbers:
6-2
=
4
Now lets put these back together and we get the expression:
5c+4
This looks like A.
Hope this helps! :D
mean = (sum of values) / (number of values)
we know mean is 13 and we are given 8 values. The ninth value is the missing x:
13 = ((sum of 8 values) + x)/9
13 = (12+10+15+12+13+15+11+15+x)/9
13*9 = 103+x
x = 14
The missing value is 14. There are 14 pillows in the last box.
The slope should be
m= 2/3 (2 over 3)
Answer:
1 penny is equal to 2.5 grams
Step-by-step explanation:
1 penny = 2.5 grams
2 pennies = 5.0 grams
3 pennies = 7.5 grams
Just add 2.5 grams every penny.
Pick any number of pennies and multiply it by 2.5 (Don't forget to add grams ( g ) at the end.
Answer:
y = x + 2
y = 2x
y = x + 5
y = 0.5x
Step-by-step explanation:
For the first three, I don't know how to explain this to you. This is very simple math, I am certain that you would have been able to do this in two minutes if you applied yourself. It would be much faster if you did the work yourself and only used brainly for things that you truly don't understand.
For the fourth answer, consider:
x is miles per 60 minutes.
y is miles per 30 minutes.
30 is half of 60, or 0.5 times 60.
Therefore, y will be equal to 0.5 times x.
y = 0.5x.
