Answer:
(A)d=20h
Step-by-step explanation:
If Kia rides her bike at 20 miles per hour.
20 miles per hour is referred to as the Kia's Speed.
Now we know that:
Given:
- Number of hours traveled=h
- Distance traveled=d
- Speed = 20 mph
Substituting these three into the formula above, we have:
Cross multiply
d=20h
<u>The correct option is A.</u>
Answer:
Step-by-step explanation:
The given equations are:
(1)
and (2)
Now, simply adding equation (1) and equation (2), we get
Now, substituting the value of x=6 in equation (2). we get
Thus, the values of x and y are 6 and 1 respectively.
In order to solve the system of solution, beau can see that in both the given equations, coefficient of y is same and is with opposite sign, thus simply adding both the equations will eliminate y and she will get the value of x and then substituting the value of x in any of the equations, she can get the value of y. With this, she can get closer to the solution.
