Answer:
This is experimental fraction question
We start with a high fraction and work downwards to a lower fraction
Reduce 10/16; = 6/12 = 1/2 observation = the fraction gets smaller by 1/5
Reduce 10/12 = 6/9 = 1/3 observation = the fraction gets smaller by 1/4
Reduce 8/8 = 3/2 observation = the fraction gets smaller by 1/3
We notice that when the fraction is whole number it reduces by 1/3
When the fraction is 3/4 it reduces by 1/4
When the fraction is 5/8 or 10/16 it reduces the fraction by 1/5
When the fraction is already half
We can prove it reduces again by a smaller than 1/5 number
1/2 = 10/20 = reduction = 6/15 = it has reduced by 3/15 = 1/6 to 1/7
This is because the numerator is reduced 40% and the denominator is reduced by 25%
Step-by-step explanation:
Answer:
1. Convert the x-coordinate from Mixed number to Decimal number.
2. Move over 2.5 units to the left.
3. From -2.5, move down 4 units.
4. Mark the point.
Step-by-step explanation:
By definition, a coordinate plane is formed by the intersection of two perpendicular lines: The y-axis (which is a vertical line) and the x-axis (which is an horizontal line). The point in which the y-axis and the x-axis intersect is known as "Origin" and has the following coordinates:
You have this point:
You can identify that the x-coordinate is:
Since it is a Mixed number you can convert it into a decimal number dividing the numerator 1 by the denominator 2 and adding the result to the Whole number part 2. Then:
And the y-coordinate is:
To plot the point:
- Start at the Origin.
- Move over 2.5 units to the left (because the x-coordinate is negative).
- Then, from -2.5 you must move down 4 units (because the y-coordinate is negative).
- Mark the point.

Answer:
-2x -8
Step-by-step explanation:
The border area will be the difference between pool+border and pool. The area of each rectangle is the product of its dimensions.
(x+3)(x-2) -(x+2)(x+1) = (x^2 +x -6) -(x^2 +3x +2)
= x^2(1 -1) +x(1 -3) +(-6 -2)
= -2x -8 . . . area of border
Answer:
6/5m
or
1 1/5m
Step-by-step explanation:
5 - 3 4/5 = x
5/1 - 19/5 = x
5/1(5/5) - 19/5 = x
25/5 - 19/5 = x
25/5 - 19/5 = 6/5
x = 6/5 or 1 1/5
