Answer:
d) A number plus eight is five times the number
Step-by-step explanation:
Keywords within mathematical phrases can be "translated" into an algebraic equation.
Keywords
First, let's define some of these keywords that can help us answer the question.
- "A number" can be replaced with the variable, x
- "Plus" is obviously used to denote addition
- "Is" is used in place of an equal sign
- "Times" is used to show multiplication
Writing Out the Expression
In the figure, we see that the blocks "x" and "8" is equal to the block "5x". So, we can say that x plus 8 is equal to 5x. Then, using the keywords above we can replace the variables and numbers.
- This creates the new sentence, "A number plus 8 is equal to five times a number."
