Answer:
Step-by-step explanation:
8/10 = x-1 / x+2
4/5 = x-1 / x+2
4(x+2) = 5(x-1)
4x + 8 = 5x -5
13 = x
there you go :)
Solve the equation in the bracket first.
(q+q+3-6)=(2q-3)
so,
q=63-(2q-3)
expand it out,
q=63-2q+3
q=66-2q
then bring over the -2q to get +2q
q+2q=66
3q=66
then simplify
q=22
A computer desk, originally priced at $83, is now on sale for $78.85
originally priced at $83. After discount the price becomes $78.85
Discount amount = $83 - $78.85 = $4.15
Decrease rate = discount amount divide by original price
Decrease rate = 
Decrease rate = 0.05
To find percent of decrease we multiply by 100
0.05 * 100 = 5%
Decrease percentage = 5%
