5b – More Practice Translating
Algebra was founded by people who needed to find answers to problems. For centuries, people
would try to solve problems without the use of variables. It wasn’t until Fibonacci in the 1400s
made using symbols (mathematical operators and variables) popular. Note the difference
between the two equations below:
Tom’s age plus 4 equals Sally’s age
T + 4 = S
Students typically have problems translating sentences into expressions or equations. Once they
get the equation written, they no longer have as much difficulty.
Translate the following into expressions or equations. Define your variables:
1. Sally is five years less than twice Tom’s age.
2. One less than Sally’s hourly wage.
3. Three times as many rocks
4. Thrice as many hours
5. Sally’s and Tom’s wages sum to be $50,000.
6. Four less pounds
7. The sum of two numbers
8. A number and 3
9. My height is 4 inches more than yours.
10. Five less than a number
11. The height of the room is half the length.
12. Twice the age of Sally.
13. Tom earns 1.25 times as much as Sally.
14. Four more pounds
Solve:
15. I ate ½ my daily peanut butter sandwiches for lunch. Had I eaten one more sandwich, I
would have eaten ⅝ my daily sandwiches. How many sandwiches do I eat daily?
16. Tom wanted Sally’s telephone number. Knowing she lived in Berrien Springs, with an
exchange number of 473, Tom just needed the last four digits. Sally slyly stated that 45 added to
his age of 30 equaled to 1000 less than half her telephone number (ignoring the exchange).
