Answer:
Step-by-step explanation:
Area of the figure = Are of square with side 8 in + 2 times the area of one triangle with base (8 - 5 = 3) 3 in and height 4 in

X could be a variable to represent "the number"
x - 9 = 4x + 5
hope this somewhat helps, not sure if its correct!
We have to decrease 22 by y%.
First we need to calculate what is y% of 22. y% of 22 simply means y% into 22 i.e.
y% x 22
= 0.01(y) x 22
= 0.22y
So 0.22 y is the y% of 22. Now we have to decrease 22 by its y% which becomes:
22 - y% of 22
= 22 - 0.22y
This expression can also be written as:
22 ( 1 - 0.01y)
See photo for drawing.
Words:
Suppose a square is 100%,
50%: the square is divided into two equal parts, and one of them is shaded, therefore it is 50%.
25%: the square is divided into 4 equal parts, and one of them is shaded, therefore it is 25%.
150%: there are two squares, each divided into 2 equal parts, and 3 of them is shadowed, therefore it is 150%.
