Writing Equations from Word Problems

What is the main focus of this video?

• Solving word problems

• Understanding fractions

• Writing equations from word problems

• Learning multiplication tables

In the first problem, what operation does the word 'sum' indicate?

• Subtraction

• Multiplication

• Addition

• Division

How do you represent one-third of a number x in an equation?

• x / 3

• 3x

• x + 3

• 1/3 * x

What is the equation for the first problem where the sum of one-third of a number x and 12 equals 23?

• x + 12 = 23

• 3x + 12 = 23

• x/3 + 12 = 23

• x/3 - 12 = 23

In the second problem, what does the variable 'c' represent?

• The weight of the truck

• The number of cars

• The weight of the car

• The combined weight of the truck and car

How is one and a half times the weight of the car represented in the equation?

• c + 1.5

• c / 1.5

• 1.5c

• 3/2 * c

What is the combined weight of the truck and car in the second problem?

• 2,500 pounds

• 3,000 pounds

• 2,000 pounds

• 1,500 pounds

In the third problem, what does the perimeter represent?

• The area of the shape

• The sum of all side lengths

• The length of one side

• The difference between the longest and shortest sides

What is the equation for the perimeter in the third problem?

• 5 + 3 + 4 = 18

• 5 + 4 + x = 18

• 5 + 3 + 4 + x = 18

• 5 + 3 + x = 18
