Diego is trying to find the value of x in 5 \sdot x = 35. He draws this diagram but is not certain how to proceed.

Complete the tape diagram .so it represents the equation 5 \sdot x = 35.

Find the value of x.

Match each equation to one of the two tape diagrams.

x + 3 = 9
3 \sdot x = 9
9 = 3 \sdot x
3 + x = 9
x = 9 - 3
x = 9 \div 3
x + x + x = 9
For each equation, draw a tape diagram and find the unknown value.

x + 9 = 16

4 \sdot x = 28
