HW: 6 - 1/3 (Week 16)

Front

What is a tape diagram?

Back

A tape diagram is a visual representation used to solve problems involving addition, subtraction, multiplication, or division. It helps to illustrate the relationships between quantities.

Front

How do you set up an equation from a tape diagram?

Back

To set up an equation from a tape diagram, identify the total quantity represented and the parts that make up that total. Use variables to represent unknown quantities and write an equation that reflects the relationships shown in the diagram.

Front

If five students each receive the same number of problems plus two additional problems, how can this be expressed mathematically?

Back

Let x be the number of problems each student receives. The total number of problems can be expressed as 5(x + 2).

Front

What is the total number of problems assigned if each of five students receives 2 additional problems and the total is 30?

Back

The equation is 5(x + 2) = 30, where x is the number of problems each student received before the additional problems.

Front

How do you find the value of x in the equation 23 = 4x + 17?

Back

To find x, first subtract 17 from both sides to get 6 = 4x. Then divide both sides by 4 to find x = 1.5.

Front

What does it mean to divide remaining items equally among a group?

Back

Dividing remaining items equally means distributing the items so that each member of the group receives the same number of items.

Front

If Lin had 90 flyers and gave 12 to each of three volunteers, how many flyers did she give away?

Back

Lin gave away 12 flyers x 3 volunteers = 36 flyers.

Front

How many flyers does Lin have left after giving some to volunteers?

Back

Lin has 90 flyers - 36 flyers = 54 flyers left.

Front

What is the equation to find out how much Andre earns each week if he saves $40 in 5 weeks after donating $2 each week?

Back

Let y be the amount Andre earns each week. The equation is 5(y - 2) = 40.

Front

How do you calculate the total amount Andre earns in 5 weeks?

Back

Total earnings = Weekly earnings x Number of weeks. If he earns y each week, then total earnings = 5y.
