The process:
8/6 = 20/x
You would have to cross multiply first.
8 20 6×20= 120
6 x 8×x=8x
Then you rearrange the equation,
120=8x
And you divide by 8 ( because it has the variable next to it)
120÷8=15
So, x=15
You can divide everything by “4” which would end up with the answer being
5-2x over 1 which would be just 5-2x
Answer:
80
Step-by-step explanation:
720/P = 9/1
Cross multiply.
9P = 720
P = 720/9
P = 80
Answer:
1.1
Step-by-step explanation:
499 - 100%
599 - x
x = 599*100/499 = 120.04
x-100% = 120.04-100 = 20.04
Answer: The price increased by 20%.
