Algebra I: Translating Sentences into Equations (Level 2 of 2)

The video tutorial focuses on translating sentences into equations, starting with basic perimeter and area problems and advancing to more complex scenarios involving rectangles, squares, cost, age, homework, distance, and the sum of numbers. The tutorial emphasizes the use of variables to represent unknowns and systematically breaks down each problem to form equations.

What is the equation for the perimeter of a triangle with sides X, 5, and 8, if the perimeter is 25?

• X + 5 + 8 = 25

• X + 13 = 25

• X + 8 = 25

• X + 5 = 25

How do you express the perimeter of a rectangle with sides X and 8, if the perimeter is 20?

• X + 16 = 20

• 2X + 16 = 20

• X + 8 = 20

• X + X + 16 = 20

If the perimeter of a square is 100 meters, what equation represents this?

• L = 25

• L + 4 = 100

• L + L + L + L = 100

• 4L = 100

A dozen donuts cost $5. What equation represents the cost of one donut?

• 12D = 5

• 5D = 12

• D = 12

• D = 5

If a trading card will be 40 years old in 7 years, what is its current age?

• C + 7 = 40

• C = 40

• C = 7

• C + 40 = 7

A student solved all but the last 2 problems in a 10-exercise assignment. How many problems did they solve?

• P = 10

• P = 8

• P + 10 = 2

• P + 2 = 10

A train traveled 463 kilometers at 132 KPH. What equation represents the time traveled?

• T = 463

• T = 132

• 463T = 132

• 463 = 132T
