Use a Tape Diagram to Determine an Unknown Value

Which equation represents the tape diagram?

• 50 = 5 + 18 + 3x

• 50 = 5 + 18 + 3

• 50 = 26x

• 50 + 3x = 5 + 18

What is the value of x in the tape diagram?

• x=15

• x=9

• x=24

• x=8

Which equation does NOT represent the tape diagram shown?

• 30 = 5(y+2)

• 30 = 5y + 10

• 5(y+2) = 30

• 30 = 5y + 2

What is the value of y in the tape diagram shown?

• y = 6

• y = 5

• y = 4

• y = 25

Which equation represents the tape diagram?

• 40 = 5w - 2

• 40 = 5(w - 2)

• 40 = w - 10

• 40 = 5 (w + 2)

What is the value of w in the tape diagram?

• w = 4

• w = 6

• w = 8

• w = 10

Which equation represents the tape diagram?

• 44 = 4(3 + x)

• 44 = 12 + x

• 44 = 4x + 3

• 44 - 3 = x

What is the value of x in the tape diagram?

• x = 11

• x = 9

• x = 8

• x = 14

Which equation represents the tape diagram?

• 4x + 39 = 87

• 43x = 87

• 87 = 4(x + 39)

• 87 = 39(4 + x)

What is the value of x in the tape diagram?

• x = 48

• x = 12

• x = 22

• x = 31.5
