To get X by itself you first bring -7 over and get X/5=-1 then multiply both sides by 5 to get X=-5
Answer:
Part A :
Robin : 50 divided by 4 = 12.5, Robin took 12.5 Weeks to get to 50 subscribers.
Dimitri : 17 divded by 7 = 2.4, Dimitri took 2.4 weeks to get to 7 subscribers.
Part B : In 7 weeks, Dimitri will have 66 subscribers, And in 4 weeks, Robin will have 66 subscribers. So after 7 weeks for Robin and 4 for Dimitri
Part C , They will have 66 subscribers. After 7 weeks Dimitri will have 66 subcribers, and after 4 weeks Robin will have 66 subscribers.
Explanation :
I have calculated out Robins and Dimitris subscribers counts with math.

Answer:
Step-by-step explanation:
First you need to find the mean of the set so 10+12+8+2=32/4=8
Mean=8
Then subtract the mean of each number and square the result
10-8=2^2=4
12-8=4^2=16
8-8=0^2=0
2-8=-6^2=36
new data set: 0,4,16,36
Next find the mean of this set of data
0+4+16+36=56/4=14 now take the square root of that mean
sqrt14=3.74
Hope this helps
