Question

Twenty more than a number is less than twice the same number

Answer 1

x+20<2x

Explanation:

20 more than a number implies that twenty must be added to the variable. Then, because it says less than you add a less than symbol. Finally, twice the same number tells you to use x again but since it’s being multiplied by 2, typing 2x makes it easier to understand.

Answer 2

The algebraic representation for the expression would look like so:

n + 20 < 2n

Given the keywords of:

• “twenty more than” (this means [insert number] + 20)

• “a number” (this stands for a variable, which any letter can be used for)

• “less than” (the way that always helps me remember is the alligator eats the greater number. It stands for this sign: “<“)

• “twice the same number” (this means “2n” because it multiplies the unknown number by 2)
