Question

Choose the equation that could be used to find two consecutive integers whose sum is 69.

n + (n + 2) = 69

n + (n + 1) = 69

n − (n + 1) = 69

n + 2n = 69

Answer 1

Answers:

The equation is: n + (n+1) = 69

The two numbers would be: 34 and 35

Step-by-step explanation:

1- getting the equation:

Let the first number be n

Since we know that the two number are consecutive, therefore, we know that they come directly after each other

This would mean that the second number is n+1

Now, we know that the summation of these two numbers is 69, this means that:

n + (n+1) = 69 ..........> the required equation

2- getting the numbers:

To get the two numbers, we will simply solve the equation we got from the first part.

n + (n+1) = 69

n+1 + 1 = 69

2n = 68

n = 34

This means that:

the first number (n) = 34

the second number (n+1) = 35

Hope this helps :)

Answer 2

the equation that could be used to find two consecutive integers whose sum is 69 is : n + (n+1) = 69

Those two consecutive integers would be : 33 and 34

33 + (34 + 1) = 69

Hope this helps
