Rearrange it so the x is on the left and y is on the right starting with the highest x value which is x^2

4x^2 + 7x - 2x - 9y + 12y
= 4x^2 + 5x + 3y

There the answers is C.

Gerry arrived at the bus stop x hours past noon. Dale arrived 4 hours later. Pat arrived at 5 P.M., x hours after Dale.
victus00 [196]

Answer:

<em>Gerry arrived at the bus station at 12:30 P.M.</em>

Step-by-step explanation:

From noon and 5:00 P.M. there are 5 hours.

Gerry, Dale, and Pat arrived at the bus stop within that interval, which means the sum of the times elapsed between their arrival times must be 5.

4 out of the 5 hours elapsed since Gerry and Dale's arrivals. This means there is only one hour left for twice x.

If twice x is one hour, then x is half an hour. Thus, the complete sequence of arrivals is:

Gerry arrived at the bus station at 12:30 P.M.

Dale arrived at the bus station at 4:30 P.M.

Pat arrived at the bus station at 5:00 P.M.

Does the expression 1.016x repersent a percent increase greater than 12% if the original amount is x? Rewrite the expression as
jeyben [28]
Let 
x---------> the original amount

we know that
<span>a percent increase of 12% of x is
  x*[100%+12%]/100------> x*[112]/100----> x*1.12

</span>1.016x
x*[100%+1.6%]/100------> x*[101.6%]/100---> 1.016x
so
1.016x-------> represent a  percent increase of 1.6% of x

so

the answer is
1.016x is not a percent increase greater than 12%
