The bill for the repair of a computer was $179. The cost for parts was $44, and the labor charge was $45 per hour. How many hour
antoniya [11.8K]

so, the repairman charges $45 for each hour of work, and $44 for the parts, now the parts are obtained only once, so that's a one-time charge of 44 bucks, let's see how the hours go.

1 hour of work................... 45 + 44(1)

2 hours of work................45 + 44(2)

3 hours of work................45 + 44(3)

4 hours of work................45 + 44(4)

x hours of work................45 + 44(x)

so the cost equation, with x = hours, C(x) = 45 + 44x.

what is x if C(x) = 179?


\bf \stackrel{C(x)}{179}=44+45x\implies 135=45x\implies \cfrac{135}{45}=x\implies 3=x

David is filling five 3/4quart bottles with a sports drinks.His measuring cup only holds 1/4 quart. How many times will David ne
vazorg [7]

Answer:

15 times

Step-by-step explanation:

Easy peasy!

So 3/4 is one whole bottle right?

The measuring cup holds only 1/4 while you need 3/4 so you fill it 3 times to fill the cup but remember you have 4 more cups to fill so you multiply 3 and 5 to get 15!!

You multiply 3 because it takes 3 measuring cups to fill a bottle and there’s 5 cups in all

Let me know if I’m wrong

Hope this helped and good luck!

Deffense [45]

Answer:

x=14.5

Step-by-step explanation:

since we know the sum of a triangles interior angles equal 180, we can subtract 66 from 180

180-66=114

6x-8+2x+6=114 - combine like terms

8x-2=114 - add 2 to both sides

8x=116 - divide by 8

x=14.5

angle a= 79

angle n=35
