Answer:
v= -2
Step-by-step explanation:
10+2v=−6(3v+5)
Step 1: Simplify both sides of the equation.
10+2v=−6(3v+5)10+2v=(−6)(3v)+(−6)(5)(Distribute)10+2v=−18v+−302v+10=−18v−30Step 2:
Add 18v to both sides.
2v+10+18v=−18v−30+18v20v+10=−30
Step 3:
Subtract 10 from both sides
.20v+10−10=−30−1020v=−40
Step 4:
Divide both sides by 20.20v20=−4020v=−2
Answer:v=−2

Step-by-step explanation:
<u>Cinematics

When an object moves at a constant speed, it can be computed as

Where x is the distance traveled and t the time needed to complete it at the constant speed v
If we wanted to compute t from the equation above, then

Elia rode her bicycle from her house to the beach at 18 km/h and then from the beach to the park at 15 km/h, taking 1 hour in the whole travel, each distance being equal. If we call b as the number of hours it took Elia to ride from her house to the beach, and p the number of hours it took her to ride from the beach to the park, then we can compute


The question doesn't ask for something in particular, so I'm helping you by solving the complete problem. We know the total time is 1 hour, so

Replacing b and p

Multiplying by 90

Simplifying and solving for x



We finally compute b and p

Answer:
0.25 miles per minute, travels 5 miles in 20 minutes
Step-by-step explanation:
First, we have to find out how many miles he can travel in a minute.
We know that he travels 15 miles every hour, and we know that one hour is 60 minutes.
- 15 mi./ 1 hr = 15 mi. / 60 minutes
So, we can divide 15 miles by 60 minutes in order to get his pace for miles per minute
- 15 ÷ 60 = 0.25 miles per minute
Then we can just multiply 0.25 miles by 20 minutes
which gives us 5 miles in 20 minutes
