Question

Which of the following will not translate as a mathematical equation?

Six plus a number is seven.
A number divided by eight, plus four.
Two less than a number is equal to twelve.
Three times a number equals fifteen.

Answer 1

A number divided by eight, plus four.

Explanation:

I would try to re-write each option as an equation, an equation would include an "=" sign.

Six plus a number is seven.

6+x=7

this is an equation.

A number divided by eight, plus four.

(x/8)+4

this is not an equation

Two less than a number is equal to twelve.

x-2=12

this is an equation

Three times a number equals fifteen.

3x=15

this is an equation

Answer 2

The statement "Six plus a number is seven" can be translated into a mathematical equation as:

6 + x = 7

The statement "A number divided by eight, plus four" can be translated into a mathematical equation as:

x/8 + 4

The statement "Two less than a number is equal to twelve" can be translated into a mathematical equation as:

x - 2 = 12

The statement "Three times a number equals fifteen" can be translated into a mathematical equation as:

3x = 15

Therefore,x/8 + 4 is not a mathematical equation.
