He electrician charges $70 per hour plus a $35 service fee. the total cost, c, for t hours of work is given by the equation c = 70t + 35. if the total cost of the electrician's last job was $245, for how many hours did he work?

3 hours

Step-by-step explanation:

Since the service fee was $35, you can take that out of the total.

Now you are left with 210.

210 / 70 = 3

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
