Question

Which equation can be used to represent the statement?

Half of a number minus seven is one and five-tenths.

Answer 1

n = 17

Explanation:

(1/2)n - 7 = 1 5/10 is the algebraic representation of that statement.

This is equivalent to n/2 - 7 = 1 5/10. The LCD is 10; we mult. all 3 terms by 10 to clear out the fractions:

5n - 70 = 15.

Adding 70 to both sides, we get 5n = 85.

Dividing both sides of this result by 5, we get n = 17.
