Whats 15= -15 - 8u equals to?

Mathematics
1 answer:
Nostrana [21]3 years ago
4 0

Method

15 = - 15 - 8u Add 15 to both sides.

15 + 15 = - 15 + 15 - 8u. This step is meant to get rid of -15 on the right side.

30 = -8u Divide both sides by 8

30 / -8 = u

Note

Usually what you are trying to do is reduce an equation so that it tells you what 1 of the letters is. Since there are many things u could be, you have to choose the one that best fits your answer

u = - 3 6/8

u = - 3 3/4

u = - 3.75

u = - 30/8

u = - 15 / 4

elena55 [62]
Henry has completed 40% of his work, leaving him with a remaining 60%.

What you do is divide 20 by 50 and your answer is .4, move the decimal two places to the right to get your percent, 40. Then subtract it out of 100 and you get the remaining 60%, which essentially is your answer.
