Movie starts 7:20 PM
2 hours = 02:00
28 minutes = 00:28
1.) 2 hours and 28 minutes = 02:28
2.) Movie starts 7:20 PM
You want to find out what time the movie will end
07:20 PM (start time)
+ 02:28 (movie time)
-------------------------------------
09:48 PM (movie end)
The movie will end at 9:48 PM
Answer:
(-1,9)
Step-by-step explanation:
y = -3x + 6
y = 9
-3x + 6 = 9
-3x = 3
x = -1
y is already given as 9, but you can solve for y by plugging the x value into y = -3x + 6,
-3(-1) + 6 = 9
(-1,9)
6x+18y+12z
Hope this helps!
-10d^2 + 11d - 2
To find this, distribute the - to 7d^2 - d - 6.
This will give you a new equation of:
-3d^2 + 10d - 8 -7d^2 + d + 6
Combine like terms to get the answer above.
Hope this helps!
