Writing Algebraic Expressions
This video discusses writing algebraic expressions by turning words into math using real-world examples, or word problems.
1. From the time of her 13th to 14th birthday, Sarah gained 10 lbs. If she weighed x lbs. on her 13th birthday, how much does she weigh on her 14th birthday?
2. On her 14th birthday, Sarah compared her weight to the weight of her older brother and found that he weighed twice as much. Write an expression for the weight of Sarah's older brother.
3. A certain skyscraper in New York City is z feet. Write an expression for the height of the skyscraper in inches.
Writing Algebraic Expressions
1. The surface of a table is a rectangle with width w inches and length l inches. Write an expression for the area of the surface of the table.
2. 5 inches were cut off both width and length of the table. Write an expression for the area of the surface of the table after being cut.
3. A family of 6 is going out to the movies. The price of a ticket is different for children and adults. The price for an adult ticket is x, while the price of a child's ticket is y. If there are 2 adults and 4 children, how much does the family pay for tickets?
