Exercises Expressions, exponents and radicals

Example 2.24 from Prealgebra, 2.2 Evaluate, Simplify, and Translate Expressions

Evaluate, Simplify, and Translate Expressions: example 2.24

Translate each word phrase into an algebraic expression:

ⓐ Eight more than $y$
ⓑ Seven less than $9 z$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
ⓐ The key words are more than. They tell us the operation is addition. More than means “added to”.
$\begin{array}{l} Eight more than y \\ Eight added to y \\ y + 8 \end{array}$

ⓑ The key words are less than. They tell us the operation is subtraction. Less than means “subtracted from”.
$\begin{array}{l} Seven less than 9 z \\ Seven subtracted from 9 z \\ 9 z - 7 \end{array}$

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Translate each word phrase into an algebraic expression:

ⓐ Eleven more than $x$
ⓑ Fourteen less than $11 a$

How did it go?
