Answer:
I think the answer is D.
Step-by-step explanation:
Five plus two times a number means 5 + 2n vice versa.
M*10-m*2=8
10m-2m=8
8m=8
Divide both sides by 8:
m=8
Fill in the m's:
1*10-1*2=8
10-2=8
8=8
Hope this helps :)
Answer:
No
Step-by-step explanation:
The inverse function of f(x) is x+7
Given:
Sharon uses 6.3 pints of blue paint and white paint to paint her bedroom walls.
of this amount is blue paint and the rest is white paint.
To find:
The pints of white paint did she use to paint her bedroom walls.
Solution:
We have,
Total paint used = 6.3 pints
Blue paint =
of total paint used
= ![\dfrac{4}{5}\times 6.3](https://tex.z-dn.net/?f=%5Cdfrac%7B4%7D%7B5%7D%5Ctimes%206.3)
= ![5.04](https://tex.z-dn.net/?f=5.04)
White paint = Total paint used - Blue paint
= ![6.3-5.04](https://tex.z-dn.net/?f=6.3-5.04)
= ![1.26](https://tex.z-dn.net/?f=1.26)
Therefore, Sharon uses 1.26 pints of white paint to paint her bedroom walls.
