Answer:

C = $137.50

Step-by-step explanation:

Okie dokie, so we already know he charges $50 just for a service call, plus 25 per hour, so let's say the total charge is C.

Now, let's make an equation:

C = 50 + 25(3.5)

Now, multiply 25 and 3.5 together:

C = 50 + 87.5

Now we just combine the like terms:

C = $137.5

Hope this helps :)

3a-13=47 a= pls help ive been stuck on this for an hower
patriot [66]

Hey there!

Explanation:

First, you had to do is add by 13 from both sides of an equation.

3a-13+13=47+13

Then, simplify or add by the numbers.

47+13=60

3a=60

Next, you can also divide by 3 from both sides of an equation.

\frac{3a}{3}=\frac{60}{3}

And finally, simplify and divide by the numbers,

60/3=20

*The answer must have a positive sign.*

\boxed{a=20}

Hope this helps!

What is the length of side b?<br><br><br><br><br><br><br><br><br> Thank u
dimulka [17.4K]
My guess is length of side B would be 12. This is my estimation, I remember a bit on how to do these but since it’s a triangle, I’m thinking the sides are going to be 1/2 of the base. In this case, the base is 24, so the sides should be 12.
