Remember you can do anythingn to an equation as long as you do it to both sides
2-5x=-18
minus 2 both sides
2-2-5x=-18-2
0-5x=-20
-5x=-20
times both sides by -1
5x=20
divide both sides by 5
(5x)/5=20/5
(5/5)x=4
1x=4
x=4
Answer:
It's 2b/3
Step-by-step explanation:
.81 as a fraction is 81/100
It is 81/100 because you need to count the place of the number after the decimal, in this case it is the hundredths. 100 will be your denominator. Then you move the decimal over to the right 2 times and get .81------>>> 81.
81 is your numerator. Your answer is 81/100
