The length of a rectangles is 3 inches less than the width. If the perimeter of the rectangle is 14 inches, find the dimensions.

The answer would be 5 inches for the width and 2 inches for the length of the rectangle.

Step-by-step explanation:

The first step would be to write an equation:

2x+ 2(x-3) = 14 inches

Next do the distributive property:

2x+ 2(x-3) = 14 inches ---> 2x+ 2x-6 = 14 inches

After that, combine like terms:

2x+ 2x-6 = 14 inches ---> 4x-6 = 14 inches

Then, add 6 to both sides:

4x-6 = 14 inches ---> 4x-6+(6) = 14 inches+(6) ---> 4x = 20 inches

Following this, divide both sides by 4:

4x = 20 inches ---> 4x÷(4) = 20 inches÷(4) ---> x = 5 inches

You now have the side length of the rectangle's width.

Lastly, find the length.

5 - 3 = 2 inches

To double-check, check with the equation.

2x+ 2(x-3) = 14 inches ---> 2(5)+ 2(5-3) = 14 inches --->

2(5) +2(2) = 14 inches ---> 10+4 = 14 inches ---> 14=14 inches

The answer is correct.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
