The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than an unknown number of inches.
If the area of the rectangle is 22 square inches, what is the value of the unknown number?
Given:
Short sides of a rectangle = 2 inches.
Area of the rectangle = 22 square inches.
The long sides of the same rectangle are three less than an unknown number of inches.
To find:
The unknown number.
Solution:
Let x be the unknown number. Then the longer side of the rectangle is (x-3) inches.
We know that the area of a rectangle is
[tex]A=length\times width[/tex]
The area of the rectangle is 22 square inches.
[tex]22=2(x-3)[/tex]
Divide both sides by 2.
[tex]11=x-3[/tex]
Add 3 on both sides.
[tex]11+3=x-3+3[/tex]
[tex]14=x[/tex]
Therefore, the value of the unknown number is 14.

What are the steps for 2x+1=7
Answer:
x = 3
Step-by-step explanation:
Step 1:
Subtract 1 from both sides
2x + 1 = 7
2x + 1 - 1 = 7 - 1
2x = 6
(1 - 1 will cancel itself out on the side with the variable.)
Step 2:
Divide both sides by 2
2x = 6
2x ÷ 2 = 6 ÷ 2
x = 6 ÷ 2
(2 divide by 2, will cancel itself out on the side with the variable.)
Step 3:
Solve for x
6 ÷ 2 = 3
x = 6 ÷ 2 = 3
x = 3

30 is 120% of what number? show ur work
Answer:
30 is 120% of 25
Step-by-step explanation:
30 = 120% of y
[tex]\frac{120}{100}[/tex] × y = 30
After multiplying both sides by 100 and dividing both sides by 120, we have
y = 30 × [tex]\frac{100}{120}[/tex]
y = 25

A rectangle's length is three times its breadth x metres. Write an expression
for the rectangle's:
a) perimeter
b) area
Answer:
1. Perimeter = 8x m
2. Area = 3x² m²
Step-by-step explanation:
From the question given above, the following data were obtained:
Breadth (B) = x m
Length (L) = 3B = 3x m
Perimeter (P) =?
Area(A) =?
1. Determination of the perimeter of the rectangle.
Breadth (B) = x m
Length (L) = 3x m
Perimeter (P) =?
P = 2(L + B)
P = 2(3x + x)
P = 2(4x)
P = 8x m
Thus, the perimeter of the rectangle is 8x m
2. Determination of the area of the rectangle.
Breadth (B) = x m
Length (L) = 3x m
Area(A) =?
A = L × B
A = 3x × x
A = 3x² m²
Thus, the area of the rectangle is 3x² m²
