WebLet's look at an example in which the expression consists of more than one number and/or operation. Example 3: Write each phrase as an algebraic expression using the variable n. Phrase. Expression. five more than twice a number. 2n + 5. the product of a number and 6. 6n. seven divided by twice a number. WebThen 4 times this unknown number is 4X. 5 more than 4 times the unknown number is 4X + 5. And you are told that this equals the unknown number increased by 20 which is X + 20. So you can write this in equation form as:. 4X + 5 = X + 20. Collect the X terms on the left side. You can do this by subtracting X from both sides of this equation to get:.

WebJan 12, 2016 · Explanation: If we choose the number to be n then 5 more than is 5 added to the number. hence: n + 5. Answer link. WebFeb 28, 2024 · It's proven more difficult than I thought. One problem I have is my inability to visualize how I'm moving back and forth on the number line when I'm multiplying $0.5 \times 0.5 = 0.25$. When one multiplies, one is simply doing continuous addition. For example, $3$ times $5$ is merely $3 + 3 + 3 + 3 + 3 = 15,$ or $5 + 5 + 5 = 15$. You're adding ... WebSo, since nickel is worth 5 cents, we multiplied 0.05 by the number of nickels (n) and multiplied 0.25 by the number of quarters (q) since a quarter is worth 25 cents. We added both algebraic expressions and set it equal to the total value of the coins. This setup, however, results in Equation #2 having two variables. popular with young people
