Question

starting with 17, show one way to make an expression with a sum
17 + 20 + 3
now, use the expression above to complete the equation.
17 + ? = 40

Explanation:

Step1: Analyze the given expression

The expression \(17 + 20 + 3\) is given. First, we can simplify \(20+3\) which is part of the sum.
\(20 + 3=23\)

Step2: Relate to the equation

We need to find the number \(x\) such that \(17+x = 40\). From the expression \(17+20 + 3\), we know that \(20 + 3=23\), so \(x = 23\) (since \(17+23=40\)). Alternatively, we can solve for \(x\) using the equation \(x=40 - 17\).
\(40-17 = 23\)

Answer:

\(23\)
