Barbra can walk 3,200 meters in 24 minutes. How far can she walk in three minutes.
lisabon 2012 [21]

Answer:

Step-by-step explanation:

To find how far she can walk in 3 minutes, we need to find how fast she can walk in 1 minutes. We do this by dividing the distance she walked by the time she walked. Lets do so.

3200/24=133.33

She walks 133.33 meters per minute. Now to find her distance in 3 minutes w multiply this number by 3.

133.33*3=400

Barbra walks 400 meters every 3 minutes.

Solve equation 3k+45=8k+25
Brrunno [24]

Answer:

k=4

Step-by-step explanation:

First, we can subtract 3k on both sides. It is ultimately easier to start by subtracting the term with a variable. This would result in 45=5k+25. Then, we can subtract 25 on both sides to get closer to isolating k. This becomes 20=5k. We can then divide by 5 on both sides. This means that k=4.

What is the equation for the values in the table
devlian [24]

Step-by-step explanation:

Taking any two points through which the line passes;(-10,-3) and (-5,-1)

The equation of the line is given by

\frac{y2 - y1}{x2 - x1}  =  \frac{y - y1}{x - x1}

=>  \frac{ - 1 - ( - 3)}{ - 5 - ( - 10)}  =  \frac{y - ( - 3)}{x -  ( - 10)}  =  \frac{y + 3}{x + 10}

=>  \frac{ - 1 + 3}{ - 5 + 10}  =  \frac{y + 3}{x + 10}

=>  \frac{2}{5}  =  \frac{y + 3}{x + 10}

=> 5(y + 3) = 2(x + 10)

=> 5y+15 = 2x+20

=> 5y =2x+5

=> y= \frac{2}{5} x + 1

option C
