Answer:
The answer is 135
Step-by-step explanation:
We can use formula: 162...120% since the price was increased by 20% which means it is 120%
So: 162...120%
x.... 100%
120x = 16200 => x = 135
Answer:
x either equals to 4 of 9 so you can write it like x=4, 9
Step-by-step explanation:
Start by simplifying each sides of the equation.
x^2-13x+36=0
Then factor the left side of the equation.
(x-4)(x-9)=0
Set factors equal to 0
x-4=0 or x-9=0
x=4 or x=9
the answer is 21/77 because you multiplied 11 by 7 to get 77, you multiply 7 by which gives you 21/77
