Question

m6|l3 reasoning about contexts with strip diagrams (part 2)
write an equation to show that 24 is equal to 4 plus 2 groups of a.
diagram: a strip divided into three parts: 4, a, a, with total 24
24 = 4 + a + a
blank = blank + blank
options: 3a, 2a, 4, 2, 24

Explanation:

Step1: Simplify like terms

Combine the two \(a\) terms: \(a + a = 2a\)

Step2: Rewrite the equation

Substitute the simplified term into the original equation.

Answer:

\(24 = 4 + 2a\)
