Question

Use deductive reasoning to show that the following procedure produces a number that is three times the original number. Procedure: Pick a number. Multiply the number by 6, add 10 to the product, then divide the sum by 2, and finally subtract 5

Answer 1

Step-by-step explanation:

1) Let the number be 1.

2) 1 × 6 = 6.

3) 6 + 10 = 16.

4) 16 ÷ 2 = 8.

5) 8 - 5 = 3.

6) From step (1) and (5)

1 = 3

Hence proved.
