ohaa [14]

Answer:

Step-by-step explanation:

D is missing 2 ideas.

An angle can be formed by a mixture of the types of figures quoted.
An angle has common or shared endpoint.

B: to me is unclear. A line does not have an endpoint. A ray does.

A: you need to mention that the lines are coplanar.

I think, brief though it is, C is the most complete and at the same time simplest choice.

Mr. Wilson wants to park his car in his parking garage. To find the cost, he uses the equation D= 3H+6, where D represents the t

charle [14.2K]

Answer: $8\ hours$

Step-by-step explanation:

You know that Mr. Wilson uses the following equation to find the cost:

$D= 3H+6$

Then, if Mr. Wilson spent $30, you can follow these steps in order to calculate how many hours he parked in the parking garage:

1. You need to substitute $D=30$ into the given equation:

$30= 3H+6$

2. Now, you must solve for "H":

$30= 3H+6\\\\30-6=3H\\\\24=3H\\\\\frac{24}{3}=H\\\\H=8$

Therefore, based on the result, you can conclude that Mr. Wilson parked his car in the parking garage for 8 hours.
