Question

Kristy asks Lonnie to think of a number, and 3 to it, multiply the sum by 2, and then subtract 6. Let n stand for Lonnie's starting numbers. Which expression represents Lonnie's final number?

Answer 1

Answer:

2(n + 3) - 6 is the expression that represents the final number.

Step-by-step explanation:

-Given the number Lonnie thinks of at the beginning is 'n'-

1) adding 3 to n

sum = n + 3

2) multiply the sum by 2

sum = 2(n + 3)

3) subtract 6

sum =  2(n + 3) - 6.
