Answer:
6m+7.5
Step-by-step explanation:
the arithmetic mean is the average of two numbers
it is given that a is average of 6m and 10
so ![a=\frac{6m+10}{2}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B6m%2B10%7D%7B2%7D)
b is the average of 4m and 4
so ![b=\frac{4m+4}{2}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B4m%2B4%7D%7B2%7D)
c is the average of 14m and 16
so ![c=\frac{14m+16}{2}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B14m%2B16%7D%7B2%7D)
now the average of a ,b and c is given by
![average=\frac{a+b+c}{3}=\frac{\frac{6m+10}{2}+\frac{4m+4}{2}+\frac{14m+16}{2}}{3}=6m+7.5](https://tex.z-dn.net/?f=average%3D%5Cfrac%7Ba%2Bb%2Bc%7D%7B3%7D%3D%5Cfrac%7B%5Cfrac%7B6m%2B10%7D%7B2%7D%2B%5Cfrac%7B4m%2B4%7D%7B2%7D%2B%5Cfrac%7B14m%2B16%7D%7B2%7D%7D%7B3%7D%3D6m%2B7.5)

Answer:
a^3b^4
Step-by-step explanation:
You have 3 a's, so that would be
![a^{3}](https://tex.z-dn.net/?f=a%5E%7B3%7D)
and you have 4 b's so that would be
![b^4](https://tex.z-dn.net/?f=b%5E4)
so putting it together gives you
![a^3b^4](https://tex.z-dn.net/?f=a%5E3b%5E4)
Answer:
y = 2x - 4.
With a slope of 2, you multiply 2 by X, and then subtract y-intercept.
