Answer:
Step-by-step explanation:
(7x-3)(12x-7)
we are solving for x and we are multiplying.
we start with the x's 7x*12x= 84x
-3*-7=21
so now we have
84x+21=0
the 0 is a placer for answering the question
we minus 21 to both sides
84x=-21
now we divide
84/-21= -4
x=-4
Answer:
$80
Step-by-step explanation:
First you take 500 and multiply by 16% or .16.
You should get 80.
A tip for the future is when you have a percentage just move the decimal place to the left twice.
ie. 50%=.50, 125%=1.25, 2%=.02
I hope this helps :)
