A bookcase is to have 5 shelves including the top. The height of the bookcase is to be 3 feet more than the width and only 20 feet of lumber is available. Use an equation to determine the width and height of the bookcase?

The width and height is 1.375 and 4.375 respectively

Step-by-step explanation:

The computation of the width and height of the book case is shown below:

Let the width be w

And, the height be h

So, the following equations should be made

5w+3h=20 (i)

h = w + 3(2)

Now

put the value of h in equation (1)

5w + 3(w + 3) = 20

5w + 3w + 9 = 20

8w = 20-9

8w = 11

w = 11 ÷ 8

= 1.375

And, the height would be

= 1.375 + 3

= 4.375

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
