Step-by-step explanation:

Answer:
15..
Step-by-step explanation:
4, 10, 14, 18, 22, 22
Mean = (4 + 10 + 14 + 18 + 22 + 22)/6
= 90/6
= 15.
Number to be added, 'y'
For the mean to be the same
(90 + y) / 7 = 15
90 + y = 15 × 7
90 + y = 105
y = 105 - 90
= 15
5x-13=15+7x
-13=15+2x
-28=2x
-14=x
100/40×20.
100/40=2•5
2•5×20=50
the answer is 50
