Question

Use the variable h, to write an expression representing the difference of three times a number and two

Answer 1

Answer:

3h - 2

Step-by-step explanation:

An expression is a mathematical phrase using variables, such as 'h', and operations, such as addition, subtraction or multiplication.  An expression does not include the equal sign (=).

The problem asks you to use the variable 'h' which we can substitute for 'a number' in the verbal description.  Also, 'difference' is a word used for the operation of subtraction.  'Times' is a word that we use for the operation of multiplication.  So, 'three times a number' = 3h.  'The difference of three times a number and two'  = 3h  - 2.
