The length of a rectangle is 5 inches less than 4 times the width. The perimeter is 110 inches. Find the length and the width.

nataly862011 [7]

Answer:

Length = 43 inches
Width = 12 inches

Step-by-step explanation:

Perimeter of a rectangle = 2 * ( L + W)

The length of a rectangle is 5 inches less than 4 times the width.

Assume the width is x. Length is:

4x - 5

Equation is therefore:

2 * (4x - 5 + x) = 110

4x - 5 + x = 110/2

5x - 5 = 55

5x = 55 + 5

x = 60/5

x = 12 inches

If width is 12 inches, then length is:

= 4x - 5

= 4 * 12 -5

= 43 inches

Please simplify: −23d+81≤−98d+1

Strike441 [17]

$- 23 d + 81 \leq -98 d + 1$

Subtract 81 from both sides :

$-23 d + 81-81 \leq -98d+1 -81$

$-23d \leq -98d-80$

Add 98d to both sides:

$-23d +98 d \leq -98d-80+98d$

$75d \leq -80$

Divide both sides by 75 :

$\frac{75d}{75} \leq \frac{-80}{75}$

$d \leq =- \frac{16}{15}$

hope this helps!.
