Jared and Pedro walk 1 mile in about 15 minutes. They can keep up pace for several hours. About how far they walk in 65 minutes
VladimirAG [237]
<h2><u>Answer:</u></h2>

Jared and Pedro walked a total of <u>4.3 miles</u>

<h2><u>Step-by-step explanation:</u></h2>
  • The equation for distance is <u>speed = distance ÷ time.</u>
  • Rearrange the equation to make distance the subject:

        <em>(multiply both sides by time)</em>

<em>         </em><u>Distance = Speed × Time</u>

  • Convert your numbers into suitable units:

        1 mile ÷ 15 = <u>0.06m/minute</u>

  • Finally, substitute the numbers into the equation and solve:

        Distance = 0.06 × 65 = <u>4.3miles</u> (rounded to the nearest decimal place)

A line goes through the point (6,-2) and has a slope of -3. What is the value of a if the point (a,7) lies on the line?​
Vikki [24]

Answer:

<h2>a = 3</h2>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

From the question the slope is - 3

To find the value of a we have

- 3 =  \frac{7 -  - 2}{a - 6}  \\  - 3 =  \frac{7 + 2}{a - 6}  \\  - 3(a - 6) = 9 \\  - 3a + 18 = 9 \\  - 3a = 9 - 18 \\  - 3a =  - 9

Divide both sides by - 3

\frac{ - 3a}{ - 3}  =  \frac{ - 9}{ - 3}  \\

We have the final answer as

<h3>a = 3</h3>

Hope this helps you
