10 = ax-3b
3b+10 = ax
(3b+10)/a = (ax)/a
x = (3b+10)/a
Answer:
4.2
Step-by-step explanation:
Base Times Height
![\frac{2}{3} \div \frac{1}{8} = \frac{2}{3} \times 8 = 5.33](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20%20%5Cdiv%20%20%5Cfrac%7B1%7D%7B8%7D%20%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20%20%5Ctimes%208%20%3D%205.33)
After rounding off, Answer is 6.

Number - x
![2 |x - 3| = 3(x + 9) \\ 2 |x - 3| = 3x + 27 \\ |x - 3 | = 1.5x + 13.5](https://tex.z-dn.net/?f=2%20%7Cx%20%20-%203%7C%20%20%3D%203%28x%20%2B%209%29%20%5C%5C%202%20%7Cx%20-%203%7C%20%20%3D%203x%20%2B%2027%20%5C%5C%20%20%7Cx%20-%203%20%7C%20%20%3D%201.5x%20%2B%2013.5)
2 Answer once when it minus and one when it plus
if plus
![x - 3 = 1.5x +13.5 \\ - 0.5x = 16.5 \\ x = - 33](https://tex.z-dn.net/?f=%20x%20-%203%20%3D%201.5x%20%2B13.5%20%5C%5C%20-%20%200.5x%20%3D%20%2016.5%20%5C%5C%20x%20%3D%20%20-%2033)
if minus
![- (x - 3) = 1.5x + 13.5 \\ - 2.5x = 10.5 \\ x = - 4.2](https://tex.z-dn.net/?f=%20-%20%28x%20-%203%29%20%3D%201.5x%20%2B%2013.5%20%5C%5C%20%20-%202.5x%20%3D%2010.5%20%5C%5C%20x%20%3D%20%20-%204.2)
these are the possible numbers
So percent means parts out of 100
x%=x/100
so we jsut have to find
(red)/(total)
add 23+52+34+61+30=200
red=52
52/200
make bottom number 100
26/100=26%
answer is 26%
