[2.05] Choose the equation that could be used to find two consecutive integers whose sum is 69.
What are your choices?
To find two consecutive integers whose sum is 69, we can use the equation:
x + (x+1) = 69,
where x is the first integer and (x+1) is the next consecutive integer.
To find two consecutive integers whose sum is 69, we can let the first integer be represented by 'x', and the second consecutive integer be 'x+1'. The sum of these two integers can be expressed as the equation:
x + (x + 1) = 69
Simplifying this equation, we get:
2x + 1 = 69
This equation represents the sum of two consecutive integers being equal to 69.
One equation would be:
x+y=69, correct? (add two integers to equal 69).
But then we know the integers are consecutive, so the second integer (y) is one greater than the first interger (x). So the next number after x is x+1
So we can say y=x+1
Then follow the train:
x+y=69
x+(x+1) = 69
x+x+1 = 69
x+x = 68
x=34
Perhaps you can use the above to determine which equation from your choices would work.
