Answer:
-y + 63
Step-by-step explanation:
Let's start like by solving the order of operations, and then add our Y's:
7y + 7 + −8y + 56
Adding:
+63 - y
Simplifying:
-y + 63
Thus, our answer is -y + 63
Answer:
105 frames
Step-by-step explanation:
Given that:
At 0 seconds, the video had already played 190 frames and there are 25 frames being played per second.
When the time is equal to 
, the number of frames that are already being played is:
= 17 × 5
= 85 frames.
But recall that, the frames had already played 190 frames at 0 seconds, then the number of frames that had already been played when the time is equal to is;
=(190 - 85) frames
= 105 frames
The rectangular prism has measures 6 units by 6 units by x units,
Thus, the volume is 6*6*x = 36x (units cubed)
The surface area of the prism is
2(x*6+x*6+6*6)=2(6x+6x+36)=2(12x+36)=24x +72 (units squared.
36x=24x +72
36x-24x=72
12x=72
x=72/12=6
Answer: x=6
The way I'd do this is by elimination. Multiply 4x+y=-10 by -14x+4y=20-4x-y=105y=30y=6
As for x multiply 4x+y=-10 by -4
4x+4y=20-16x-4y=4012x=60
x=5
