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

sasho [114]

Answer:

$\displaystyle b=0.45\ h$

$\displaystyle p=0.55\ h$

Step-by-step explanation:

<u>Cinematics </u>

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

$\displaystyle v=\frac{x}{t}$

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

$\displaystyle t=\frac{x}{v}$

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

$\displaystyle b=\frac{x}{18}$

$\displaystyle p=\frac{x}{15}$

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

$\displaystyle b+p=1$

Replacing b and p

$\displaystyle \frac{x}{18}+\frac{x}{15}=1$

Multiplying by 90

$\displaystyle \frac{90x}{18}+\frac{90x}{15}=90$

Simplifying and solving for x

$\displaystyle 5x+6x=90$

$\displaystyle 11x=90$

$\displaystyle x=\frac{90}{11}=8.18\ km$

We finally compute b and p

$\displaystyle b=\frac{8.18}{18}=0.45\ h$

$\displaystyle p=\frac{8.18}{15}=0.55\ h$

A cyclist rides his bike at a rate of 15 miles per hour. what is this rate in miles per minute? how many miles will the cyclist

vladimir2022 [97]

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

0.25 × 20 = 5

which gives us 5 miles in 20 minutes
