Aplumber charges $30 for a house call and $20 per 1/2 of work. how much will the plumber charge for 4 1/2 hours of work at mrs. dimarco's house?

210$

Step-by-step explanation:

30 + (20 * 9) =

30 + 180 = 210

It's 20 * 9 because there is 8 halves in a 4, and an additional half makes it 9 halves.

20 times 9 :)

And, of course, the 30 for the house call to start off with.

Total: 210$

$210

Step-by-step explanation:

How may half hours in 4.5 hours?

4.5/0.5=9

Each half hour is worth $20.

9*20=180

step-by-step explanation:

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.
