What is the most reasonable estimate for 54% of 168<br> <br> A:8.4<br> B:46<br> C:84<br> D:110
lianna [129]
Just by estimating, 54% is a little over 1/2 of 168.  You know by that, that neither A or B is close. The real answer is 90.72, so if your instructor wants you to round up, it would be D

How to convert y = - 2\5 x to standard form
coldgirl [10]
Bring it to the form ax + by = c, where a is positive, and there are no fractions in the equation.
Here, we need to add 2/5x to both sides:
2/5x + y = 0
Then multiply everything by 5 to get rid of the fraction
2x + 5y = 0 <==
