Question

Harvey plans to use 5 ft of shelving for four shelves whose lengths are to be a series of consecutive even numbers. How many inches long should each shelf be?

Answer 1

Answer:

Shelfs will be 12 , 14 , 16 , 18 inches long

Step-by-step explanation:

5 ft of shelving

1 ft = 12 inches

=> 5ft = 5 * 12 = 60 inches

four shelves whose lengths are to be a series of consecutive even numbers

let say there lengths are

a , a + 2 , a + 4 , a + 6  inches

a + a + 2 + a + 4 + a + 6 = 60

=> 4a + 12 = 60

=> 4a = 48

=> a = 12

12 , 14 , 16 , 18

Shelfs will be 12 , 14 , 16 , 18 inches long
