Answer:
correct answer is : D. 42 + 3x - 7
Answer:
5
Step-by-step explanation:
I played a video game for 15 minutes and I lose 75 points.
So, at time = 0, point loss =0, and at time = 15 minutes, point loss = 75.
Therefore, the mean change in points per minute is = ( total loss of points / total minutes of playing the game )
= 
= 5 points per minute.
Hence, the integer 5 represents the mean change in points per minute. (Answer)
One pack is $4.50.
To make it simpler with no equations, There are 2 packs of markers in-between 3 packs and five packs.
So, $9 divided by 2 packs is 4.5$,
And to prove this scenario right,
3 packs= $13.5. (3•4.5)
5 packs= $22.5. (5•4.5)
So between 5 packs and 3 packs,
There is a difference of 9 dollars,
Hence 3 packs of markers at $13.5,
5 packs is $22.5, so that is $9 less
Than 5 packs of markers.
Therefore one pack of markers is $4.50, by dividing 22.5 by 4.5 or 13.5 by 4.5 after figuring out the previous.
The two angles add up to 180 degrees. So all you do is 180 - 35 which equals to 145 degrees

when it return to the ground , h = 0
32t -16t2 = 0 and solve for t
t = 0, 2 ....0 is the start, 2 is when it returns
