Identify all of the constants of the expression 2+6a
You read 50 pages in an hour. Your sister reads 40 pages in an hour. Explain how to find out how many more pages you read than your sister reads in 1/2 hour?A. I know that 50 • 40 = 2,000, so I read 1,000 more pages than my sister reads in 1/2 hour. B. I know that 50 ÷ 40 = 5454, 5 ÷ 4 = 1 1/4, so I read 1 1/4 more pages than my sister reads in 1/2 hour. C. Because I read 10 more pages than my sister reads in 1 hour, I read 5 more pages in 1/2 hour. D. Since 5 • 4 = 20, I read 20 more pages than my sister reads in 1/2 one half hour.

= 15/2 acres
Amount of land required for building each house = 1/4 acre
Then
The total number of
houses that can be built by the developer = (15/2)/(1/4)
= (15 * 4)/(2 * 1)
= 15 * 2
= 30
So the developer can make a total of 30 house with the quantity of land he has. The correct option among all the options given in the question is option "C".
The developer will build 30 total number of houses when the total area is acres.
The total space occupied by any object is called as its area.
The area of each house is given as acre
Total land with the developer is given as acre
The number of houses can be calculated as:
Assume the number of houses be x.
The mixed fraction in improper form can be written as:
Multiply both side by 4 to get the value of x
x = 30
Thus, the developer can build 30 plots using acres of land.

Take one of the points in the table,
like x=1 y=5
or x=2 y=7
Write them into one of the choices on the list,
and see if the result is true.
For example,
-- Take the line in table that says x=1 y=5.
-- And take the first choice on the list y = x + 3 .
-- Write '1' in place of 'x', and write '5' in place of 'y'.
-- Then you have 5 = 1 + 3 .
Is this true ? I don't think so.
So the first choice on the list can't be correct.
Try thesame point x=1 y=5 with the other choices.
You'll find one that IS correct, and that's the answer.

The sequence was following the pattern of squaring numbers that were in chronological order.
1^2=1
2^2=4
3^2=9
4^2=16
So, next number would be 5^2=25.
