Bed a is seven feet long. bed b is 7/8 of bed a. bed c is 7/8 of bed b. bed d is 7/8 of c. a. come up with an expression for the length of bed d. b. what is the length of bed d?

An expression for the length of bed D is

The length of bed D= 4.7 ft

Step-by-step explanation:

Given: Bed A is seven feet long.

⇒ The  length of bed A= 7 ft.

Bed B is 7/8 of bed A.

⇒ The length of bed B =

Bed C is 7/8 of bed B.

⇒ The length of bed C=

Bed D is 7/8 of C.

⇒ The length of bed D=

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
