The bill for the repair of a computer was $179. The cost of part was $44, and labor charge was $45 per hour. How many hours did

Cloud [144]

Alright! First you'd subtract the amount of the part ($44) from your total ($179), then you'd divide by the rate of cost ($45). Your equation would be:
($179 - $44) ÷ $45 = h.

Then you solve:
($179 - $44) = $135
($135 ÷ $45) = 3
h = 3.

The answer is 3 hours.

Solve the equation x^2+6x= -11/4

xxTIMURxx [149]

Answer:

Step-by-step explanation:

First, move the -11/4 to the other side, so the expression can equal 0.

$x^2+6x+11/4=0$

To make the equation easier to work with, multiply both sides by 4, cancelling out the fraction.

$4x^2+24x+11=0$

There are many ways to solve a quadratic equation (factoring, quadratic formula, completing the square).

Solving this equation by factoring is the easiest. Factoring with a leading coefficient greater than one can be difficult and there are many ways to accomplish it. The way I'm going to do it is to first find the factors of $4x^2$ and then the factors of 11. And then multiply across, add the middle terms (derived from multiplying) and try to make it equal 24x.

$4x^2$ : 24x 11:

2x 22x 11

2x 2x 1

24x (works)

I'll then take the factors diagonal. (2x+1)(2x+11)=0

So $x=-\frac{1}{2}, -\frac{11}{2}$
