Answer: 80% of 20 is 16. 100% of 20 is 20, therefore 80 percent of 20 equals 16. To learn how to solve 16 is 80 percent of what Number, see the step by step instructions below.
Step-by-step explanation: Hope this help :D
5h -2+ 9h
= (5h+ 9h) -2
= 14h -2
The final answer is 14h -2~
X - (9x - 10) + 11 = 12x + 3(-2x +
) equals
x = .
First, simplify brackets. / Your problem should look like: x - 9x + 10 + 11 = 12x + 3(-2x +
).
Second, simplify x - 9x + 10 + 11 to -8x + 10 + 11. / Your problem should look like: -8x + 10 + 11 = 12x + 3(-2x +
).
Third, simplify -8x + 10 + 11 to -8x + 21. / Your problem should look like: -8x + 21 = 12x + 3(-2x +
).
Fourth, expand. / Your problem should look like: -8x + 21 = 12x - 6x + 1.
Fifth, simplify 12x - 6x + 1 to 6x + 1./ Your problem should look like: -8x + 21 = 6x + 1.
Sixth, add 8x to both sides. / Your problem should look like: 21 = 6x + 1 + 8x.
Seventh, simplify 6x + 1 + 8x to 14x + 1. / Your problem should look like: 21 = 14x + 1.
Eighth, subtract 1 from both sides. / Your problem should look like: 21 - 1 = 14x.
Ninth, simplify 21 - 1 to 20. / Your problem should look like: 20 = 14x.
Tenth, divide both sides by 14. / Your problem should look like:
= x.
Eleventh, simplify
to
. / Your problem should look like:
= x.
Twelfth, switch sides. / Your problem should look like: x =
which is your answer.
Answer:
