grin007 [14]

Answer:

The given expression "The sum of two consecutive odd integers equals 12." is written as 2x + 1 + 2x + 3 = 12  and numbers are 5 and 7

Step-by-step explanation:

 Given expression : The sum of two consecutive odd integers equals 12.

We have to write the given expression mathematically and solve.

Consider the given expression "The sum of two consecutive odd integers equals 12."

Consecutive odd integers are the odd integers having difference of two in between like 3, 5, 7 etc,

we know odd numbers are of the form of (2m+1)

Thus, let two consecutive odd integers be 2x+1 and 2x+3

Then given sum of  two consecutive odd integers  is 12

mathematically written as,

2x + 1 + 2x + 3 = 12

4x+ 4 = 12

x + 1 = 3

x = 2

Thus, consecutive odd integers are 2(2)+1 = 5

and 2(2) + 3 = 7

Thus, the given expression "The sum of two consecutive odd integers equals 12." is written as 2x + 1 + 2x + 3 = 12  and numbers are 5 and 7

Ludmilka [50]
X will stand for every extra book sold

880 = 4x + 500
subtract 500 from both sides

380 = 4x
divide both sides by 4

x = 95
they sold 95 books
