Vicky came home from the matinee at 5:45 p. M. The travel time to and from the cinema was 1/2 hour each way. She spent 2 1/4 hours at the cinema. What time did she leave home.

2:30 pm

Step-by-step explanation:

Going backward, since he spent 1/2 hour  - 30minutes from the cinema to home.

5:45 - 30 = 5:15pm.

5:15pm was when the movie finished.

The movie lasted for 2 1/4 hours   = 2 hours, 1/4 hours -15 minutes

So the movie lasted for 2 hours, 15 minutes.

5: 15 - 2: 15 = 3:00pm

And it took him another 1/2 hours to cinema from his house

3:00pm - 30minutes = 2:30pm

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

your answer is d 2,500
