I’ll solve number 3.
You need to group the like terms. For example, -4n + 6n = 2n
8=2n
Now, we need to keep n by itself.
2n/2 = n
Whatever you do to one side, you need to do to the other.
8/2 = 4
So, in conclusion, n = 4.
I hope this helps for you to solve the rest!
Answer:
136
Step-by-step explanation: 34 multiplied by 4
Answer: 105
Step-by-step explanation: 25 frames is 1 second. The video already played 3 and 2/5 seconds before the player started to count 0, so you can write 3 and 2/5 seconds as an improper fraction. =(5*3)+2 / 5 = 17/5 seconds. Multiply by 25 frame. 17/5 *25 =85 frames. So according to the video counter,after 17/5 seconds,it should count 85 frames.However,at 0 seconds,it indicated a count of 190 frames. then to get the number of frames that were already in count you would subtract 85 frames from the 190 frames.
190-85=105 frames

Answer:
7/3 =k
Step-by-step explanation:
4. -7 = 3k - 3-7
Combine like terms
-3 = 3k-10
Add 10 to each side
-3+10 = 3k-10+10
7 = 3k
Divide each side by 3
7/3 = 3k/3
7/3 =k
