Mavis drives = 634 miles.
Mavis visits her grandmother 4 times.
That means, she drives 634 miles each time when she visits her mother.
One time round trip Mavis's house to her gramdmother in philadelphia = 634 miles.
If she visited 4 times, we can multiply one round trip distance by 4 or we can just add that distance four times.
Let us try it by multiplying 4 by 634 .
If we multiply 4 by 634, we get 2536.
Therefore, 2536 miles Mavis drives if she visits her grandmother 4 times.
Answer: y=38
x=38
z=109
Step-by-step explanation:
because
8x - 9y = 11 (subtract 8x from each side)
- 9y = -8x + 11 (divide -9 from each side)
y =
D. 
Answer The Answer is 80
Step-by-step explanation:
4*5=20
8*5=40
11*5=55
so 16*5=80
The solution of the system of equations contains one point
<h3>How to determine the number of solutions?</h3>
The system is given as:
x + y = 6
x - y = 0
Add both equations
2x = 6
Divide by 2
x = 3
Substitute x = 3 in x - y = 0
3 - y = 0
Solve for y
y = 3
So, we have x =3 and y = 3
Hence, the solution of the system of equations contains one point
