Answer:
i don´t know my head hurts to do that without writing it down
Step-by-step explanation:
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
(7,5) is the solution to this system.
14-3^2 x (-2)
=14-9 x (-2)
=14- (-18)
=32
Answer:
Jacqueline = 150 minutes
Cassie = 125 minutes
The answer would be 2. (The difference in length between Cassie’s longest and shortest practice sessions was greater than the difference in length between Jacqueline’s longest and shortest sessions.)
