Answer:
d = 3 c= 1/4
Step-by-step explanation:
Eq. 1) -4c + 5d = 14
Eq. 2) -4c + 3d = 8 ( the written Eq. says 40 but I am guessing it's 4c )
subtract Eq. 1 and Eq. 2
2d=6
d=3
plug 3 in for d in Eq. 1
-4c + 5(3) = 14
-4c + 15 = 14
-4c = -1
c = 1/4
Answer:
y = 2x² + 16x + 11
I hope im right... If not reaaally sorry!!
Answer:
2 hour 50 minutes
Step-by-step explanation:
Given data: Departure = 5:30 pm MST, Arrive = 9:20 pm CST
Note that MST is the time zone 1 hour before CST.
Let us convert MST into CST.
Departure = 5:30 pm MST = 6:30 pm CST
Total time travel = Departure – Arrival
= 9.20 pm MST – 6.30 pm MST
= 2 hour 50 minutes
Hence, total time travel is 2 hour 50 minutes.
