Answer:
the solution for x is -5.
Step-by-step explanation:
more of the quest pls....and more important is the brainliest
Istance squared = (X2 - X1)^2 + (Y2 - Y1)^2
<span>distance squared = (-2 - 3)^2 + (4 - -2)^2 </span>
<span>distance squared = (-5)^2 + (6)^2 </span>
<span>distance squared = 25 + 36 </span>
<span>distance squared = 61 </span>
<span>Therefore; distance = square root of 61 = 7.8 approximately </span>
<span>---- </span>
<span>since each unit represents 5 miles: </span>
<span>distance (actual) = 7.8 * 5 = 39 miles</span>
Answer:
Elena's running speed is 5 miles/hour
Explanation:
The speed is defined as the covered distance per unit time
In the problem, we have:
The distance covered is the length (circumference) of the circular track which is given as of a mile.
We are also given that she completes each lap (she completes of a mile) in of an hour
To get her speed, we will divide the distance covered by the time taken to cover this distance
This is done as follows:
speed = miles/hour
This means that:
Elena can run 5 miles each hour
