Question

Daniella wrote the equation shown to represent “four less than – 3.7 times a number is –11.9.” 4n – (–3.7) = 11.9 Explain her error, include the correct equation in your response.

Answer 1

The coefficient of the variable should be -3.7 because of the word “times.” The words “four less than” mean that 4 will be subtracted from 3.7n. “Is” represents the equals sign, and “-11.9” is the second expression. The correct equation is -3.7n – 4 = -11.9.

Answer 2

The correct equation is
`-3.7n-4=-11.9`

Explanation:

Let

n-------> the number

we know that

The equation that represent the expression “four less than
`-3.7` times a number is
`-11.9` " is equal to

`-3.7n-4=-11.9`

The equation that Daniella wrote represents the expression "
`-3.7` less than four times a number is
`11.9` "
