To determine

To write an algebraic expression for the following word phrase: “the product of 8 and $z$ plus the product of 6.5 and $y$ ”

Answer to Problem 23P

  $8\cdot z+6.5\cdot y$

Explanation of Solution

Given:

Consider the phrase “the product of 8 and $z$ plus the product of 6.5 and $y$ ”

Calculations:

“product of 8 and $z$ ” will be expressed as $8\cdot z$ ,

“product of 6.5 and $y$ ” will be expressed as $6.5\cdot y$ ,

Therefore, “the product of 8 and $z$ plus the product of 6.5 and $y$ ”, will be expressed as: $8\cdot z+6.5\cdot y$ .
