ANSWER
![\frac{a + 3}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%20%2B%203%7D%7B8%7D%20)
EXPLANATION
We want to simplify
![\frac{a + 3}{a} \div \frac{8}{a}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%20%2B%203%7D%7Ba%7D%20%20%5Cdiv%20%20%5Cfrac%7B8%7D%7Ba%7D%20)
We multiply the first fraction by the reciprocal of the second fraction to obtain,
![\frac{a + 3}{a} \times \frac{a}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%20%2B%203%7D%7Ba%7D%20%20%20%5Ctimes%20%20%5Cfrac%7Ba%7D%7B8%7D%20)
We cancel the common factors to get,
![\frac{a + 3}{1} \times \frac{1}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%20%2B%203%7D%7B1%7D%20%20%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B8%7D%20)
This gives us,
110
101 thats the answer if I understood correctly
Answer:
Step-by-step explanation:
(2 , 0) ; (0, 1)
Slope = ![\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C)
![= \frac{1-0}{0-2}\\\\=\frac{1}{-2}\\\\\\=\frac{-1}{2}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1-0%7D%7B0-2%7D%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B-2%7D%5C%5C%5C%5C%5C%5C%3D%5Cfrac%7B-1%7D%7B2%7D)
m = -1/2 ; (2 , 0)
Equation of the line : y - y1 = m(x - x1)
![y - 0 = \frac{-1}{2}(x-2)\\\\ y = \frac{-1}{2}x - 2*\frac{-1}{2}\\\\\\ y = \frac{-1}{2}x+1](https://tex.z-dn.net/?f=y%20-%200%20%3D%20%5Cfrac%7B-1%7D%7B2%7D%28x-2%29%5C%5C%5C%5C%20%20%20%20%20y%20%3D%20%5Cfrac%7B-1%7D%7B2%7Dx%20-%202%2A%5Cfrac%7B-1%7D%7B2%7D%5C%5C%5C%5C%5C%5C%20%20%20%20%20y%20%3D%20%5Cfrac%7B-1%7D%7B2%7Dx%2B1)
slope = (-1/2)
y - intercept = 1
Answer:
70
Step-by-step explanation:
Chem : Phy = 3: 2
Since we have 105 pupils studying Chem and let's say we have x students stuyding Phy.
We have :![3:2=105:x](https://tex.z-dn.net/?f=3%3A2%3D105%3Ax)
![3x=210](https://tex.z-dn.net/?f=3x%3D210)
x=70
