Answer:

  • A and C are correct choices

========================

The difference between two consecutive integers is 1.

Test it with the given choices

A) x + (x + 1) + (x + 2) = 42,

  • Yes

B) x + (x + 2) + (x + 4) = 42

  • No, the difference between the pairs is 2 not 1.

C) (x minus 1) + x + (x + 1) = 42

  • Yes

D) (x minus 2) + x + (x + 2) = 42

  • No, the difference between the pairs is 2 not 1.

E) x + 2 x + 3 x = 42

  • No, here is the multiples of integers and the difference between the pairs is x not 1.

Answer:

x + (x + 1) + (x + 2) = 42

(x minus 1) + x + (x + 1) = 42

Step-by-step explanation:

Integer: A whole number that can be positive, negative, or zero.

Consecutive integer:  Integers that follow each other in order.

Let x be an integer.

Consecutive integers of x are one more or one less than each other in order.

  • x + (x + 1) + (x + 2) = 42

This equation represents 3 consecutive integers as each value is one more than the previous value.

  • x + (x + 2) + (x + 4) = 42

This equation does not represent 3 consecutive integers as each value is 2 more than the previous value.

  • (x minus 1) + x + (x + 1) = 42

This equation represents 3 consecutive integers as each value is one more than the previous value.

  • (x minus 2) + x + (x + 2) = 42

This equation does not represent 3 consecutive integers as each value is 2 more than the previous value.

  • x + 2 x + 3 x = 42

This equation does not represent 3 consecutive integers as each value is x more than the previous value.
