Answer:
The value of x is 85.
Step-by-step explanation:
We know
Sum of all observations/ No. of observations = Mean
∴ (x) + (x + 3) + (x + 5) + (x + 7) + (x + 10)/ 5 = 90
⇒x + x + 3 + x + 5 + x + 7 + x + 10 = 450
⇒5x + 25 = 450
⇒5x = 425
⇒x = 85
If you find any mistake, please let me know in the comments :)
Hope this helps!

Answer:
x = 85
Step-by-step explanation:
Mean = Sum of observatins / Total number of observations
So mean = (x + x+3 + x+5 + x+7 + x+10) / 5 = 90
=> (5x+25) / 5 = 90
=> 5x+25 = 450
=> 5x = 425
=> x = 85
