You would need to do 48×2=96 pages an hour .it would be 96 pages an hour because for half an hour it is 48 pages so you need to do times two to make it one full hour.i hope this helps if you dont get how I explain it please tell me or if you already have an answer
You haven't provided any value, but I can tell you the solution set for the inequality.
First of all, expand both sides:
Add 3x to both sides:
Add 6 to both sides:
Which is of course equivalent to
Divide both sides by 9
So, every number smaller than 2 is part of the solution of this inequality.
Answer:
The answer to your question is 0.057 ha
Step-by-step explanation:
Data
Kilocalories needed for a person per day = 2450
Kilocalories produced per hectare = 15737000
Process
1.- Calculate the number of kcal needed per a person for a year
2450 kcal ----------------- 1 day
x ----------------- 365 days
x = (365 x 2450) / 1
x = 894250 kcal
2.- Calculate the amount of land needed
15737000 kcal ------------- 1 ha
894250 kcal ------------ x
x = (894250 x 1) / 15737000
x = 0.057 ha
