Answer:
x =4
Step-by-step explanation:
They need serious help
go outside, experience the world
anyway
their total number per day is 17+21=38
so then if d=number of days, then the combined number of posts will be 38 times d or 38d
The decrease is (95-68) = 27 .
As a fraction, the decrease is 27/95 of the original amount.
To change any fraction to a decimal, do the division:
(27) divided by (95) = 0.2842...
To change any decimal to a percentage, move the
decimal point two places that ==> way:
0.2842... = 28.42... %
The answer is 8.513 which is to 3 decimal places
100 more than 146 is 246
add 100 to 146 and it becomes 246
