If a system has at least one solution, it is said to be consistent .
If a consistent system has an infinite number of solutions, it is dependent
I believe y equals 4.
9/4y - 12. = 1/4y - 4
+ 12. +12
9/4y. = 1/4y + 8
- 1/4y. - 1/4y
8/4y. = 8
2y. = 8
2. 2
Y = 4
The answer is 10.8. You turn 10 4/5 into 54/5. Then you divide 54 by 5.
I hope this helps you
distance=speed×time
first cars time t
second cars time t+3
same distance
distance=55.t
distance=40. (t+3)
55t=40 (t+3)
55t-40t=120
15t=120
t=8
t+3=11
10 separated into 5 groups is 10/5
5 goes into 10 2 times.
10/5=2
