Answer:
x=10
Step-by-step explanation:
Answer: 31500 to 38500
Step-by-step explanation:
Lets find lower limit of guess
35000 - ( 35000 * 10% )
= 31500
Upper limit of guess
35000 + ( 35000 * 10% )
= 38500
So your guess can be anything between these two values.
56 pages/4 hours = 126 pages/x pages
Then you cross multiply
56*x =4*126 ---> 56x=504
Then you divide 56 to both sides
56x/56=504/56
The 56 cancels on the left side and then you get
x=9
So your proportion are:
56 pages/4hours=126 pages/9 hours
Answer: 38
Step-by-step explanation:
Since the new side will be 2 times the length, 2 x 19 = 38.
