Favorite Answer
11.) 6% of ___?= 18
6/100*x = 18
6x / 100 = 18 both sides multiplied by 100
6x = 180
x = 30
12.)3(x+4) – 6x < -9 3x + 12 -6x < -9 -3x <-9 -12 -3x <-21 both sides divided into (-3) x > 7
Hey, anything else?
If you put up what you got as the answers, then i can double check for you.
-For the percentages, set up an equation including x, and solve for x. Remember that something like 6% is = 6/100.
-For the inequalities, you can solve for x just like in an equation with =.
that wont help much on a test.
maybe you should ask more specific questions, like HOW to do it.
ask a specific question, and i will help you.
