Answer:
80 mph
Step-by-step explanation:

<u>First leg of trip</u>
- Speed = 64 mph
- Time = 3 hours

<u>Second leg of trip</u>
- Speed = 92 mph
- Time = 4 hours


To find the average speed:

The answer is d, (-2.5,0.75)
You will have to use trig to solve this:
The side you have is adjacent to the known angle
The side you are looking for is opposite the known angle
^^^This means you need to use tan:
tan(24) = 
.445222 = 
^^^input tan(24) into calculator, then multiply 12 to both sides to isolate and solve for x
5.3 ≈ x

Answer:
7.75
Step-by-step explanation:
1 mg = 0.001 g

Answer: 5-10g+20h
Step-by-step explanation:
You can rewrite as 5(1-2g+4h). 5x1 equals 5, 5x2g=10g, 5x4h=20h, then you get 5-10g+20h
