First, convert any mixed numbers to fractions. An easy way to convert:

<h3>
=</h3>

Then, apply the fractions formula for division.

Then, simplify.

Okay, to find length CE, your going to know the value of x. Length BC + CE = BD + DE.3x+47+x+26=27+x+10Simplify the equation to get4x+73=37+xyou can choose one of four ways to continue, but I will choose to subtract x3x+73=37Subtract 73 from both sides of the equal sign3x=-36divide by 3 on both sides of the equal sign to get the value of xx=-12Now, plug in -12 for x in length CE to get -12+26=14
It would be d, since he will pay $12 per hour, equivalent to 12×h or 12h.
Answer:
In alphabetic order:
x can be found with pythagorean theorem, since triangle ADC is right in D.

y and z are 7 times respectively the sine and cosine of angle ACB.

Finally,
can be calculated by determining the arc sine (or inverse sine) of the ratio CD over AC
