Answer:
They gained 4 1/2 yards
Step-by-step explanation:
It was a positive gain because they didn't go back.
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.
He must get a 65 as a minimum grade on his third test to get an average of 70.
