Answer:
B and D
Step-by-step explanation:
First, you have to solve the first equation. (Hint: you use the distributive property.)
2(5x + 2 + x)
10x + 4 + 2x
12x + 4
We can already see that B is correct and A is incorrect.
Now to solve C and D.
C = 2(5x + 3)
10x + 6
This is incorrect.
D = 2(6x + 2)
12x + 4
This is correct.
Answer:
1/3
Step-by-step explanation:
There are 4 brown M&Ms and 12 M&Ms in total.
Since both 4 and 12 are divisible by 4,
4/12 = 1/3
To find the mean of a dot plot, add up all of the data and divide by how many numbers there are.
In this case, the data added up is 4 + (5 x 4) + (6 x 3) + (7 x 2) + 10
4 + (5 x 4) + (6 x 3) + (7 x 2) + 10 = 66
With this information, we can now find the mean.
66/11=6
Therefore, the mean is 6. Hope this helps! Feel free to ask any questions.
