Five less than twice what negative number squared is 157?

1 answer:

3 0

Five less than twice what negative number squared is 157 <- put into an expression
-5 + 2(-x^2) = 157
Now simplify:
-5 + -2x^2 = 157
-2x^2 = 162
-2x^2 - 162 = 0
2x^2 + 162 = 0
x^2 + 81 = 0

There are 80 members of the show choir. For a fund raiser 95% of the members raised money, how many members did NOT raise money.

Mumz [18]

To find out how many did not raise money, we need to find the percentage that did not raise money and multiply that by the total number of members.

If 95% raised money, 5% did not raise money.

0.05 x 80 = 4 members did not raise money
