Here is an equation: \(x + 4 = 17\)
- Draw a tape diagram to represent the equation.
- Which part of the diagram shows the quantity \(x\)? What about 4? What about 17?
- How does the diagram show that \(x+4\) has the same value as 17?
Diego is trying to find the value of \(x\) in \(5 \boldcdot x = 35\). He draws this diagram but is not certain how to proceed.
- Complete the tape diagram so it represents the equation \(5 \boldcdot x = 35\).
- Find the value of \(x\).
Match each equation to one of the two tape diagrams.
- \(x + 3 = 9\)
- \(3 \boldcdot x = 9\)
- \(9=3 \boldcdot x\)
- \(x = 9 - 3\)
- \(x = 9 \div 3\)
- \(x + x+ x = 9\)
For each equation, draw a tape diagram and find the unknown value.
\(4 \boldcdot x = 28\)
