Ok so he will need to have $630 to pay his sister back and buy the bike. Now do 630 divided by 30 to get 21 weeks of saving to get enough money
5 + x = 5x
Hopefully this is what you meant.

Answer:0.154
Step-by-step explanation:
Given
Let factory A produces 2c unit
B produces 7c units
C produces c units
Probability a computer is chosen from A is ![\frac{2}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B10%7D)
![From B=\frac{7}{10}](https://tex.z-dn.net/?f=From%20B%3D%5Cfrac%7B7%7D%7B10%7D)
![from C=\frac{1}{10}](https://tex.z-dn.net/?f=from%20C%3D%5Cfrac%7B1%7D%7B10%7D)
Probability Of a defective computer ![=\frac{2}{10}\times 0.035+\frac{7}{10}\times 0.048+\frac{1}{10}\times 0.046=0.0452](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2%7D%7B10%7D%5Ctimes%200.035%2B%5Cfrac%7B7%7D%7B10%7D%5Ctimes%200.048%2B%5Cfrac%7B1%7D%7B10%7D%5Ctimes%200.046%3D0.0452)
Probability that it came from factory A ![=\frac{\frac{2}{10}\times 0.035}{\frac{2}{10}\times 0.035+\frac{7}{10}\times 0.048+\frac{1}{10}\times 0.046}=0.154](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Cfrac%7B2%7D%7B10%7D%5Ctimes%200.035%7D%7B%5Cfrac%7B2%7D%7B10%7D%5Ctimes%200.035%2B%5Cfrac%7B7%7D%7B10%7D%5Ctimes%200.048%2B%5Cfrac%7B1%7D%7B10%7D%5Ctimes%200.046%7D%3D0.154)
Answer:
5x + 2y = 9
Step-by-step explanation:
Find the slope of the line that is perpendicular to 2x - 5y = 7 :
m= ![\frac{-5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-5%7D%7B2%7D)
Find the y - intercept of the function:
b = ![\frac{9}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B2%7D)
substitute m=
and b =
into y = mx + b :
y =
+ ![\frac{9}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B2%7D)
y = 5x + 2y = 9
