Answer:
60%
Step-by-step explanation:
18 divided by 30 is 0.6, and then just move the decimal two to the right and you have 60.
X=4
(X+20)/2 = 3x
Multiply everything by 2 to cancel out the 2; therefore, (x+20)= 6x
Now solve for x,
20= 6x-x
20= 5x
Divide everything by 5 to solve for x,
20\5 = 5x/5
4=x
13,200
because you would take 165,000 and mulitply it by .08 (because it is a percent just move the decimal 2 places to the left to get it in decimal form) which would then give you 13,200
