Question

find the value of y in the diagram below.
diagram showing a rectangle labeled 40, followed by three rectangles each labeled y, with the total length labeled 52
answer attempt 1 out of 2
y = input box submit answer

Explanation:

Step1: Set up the equation

From the diagram, we know that \( 40 + 3y = 52 \) (since there are three \( y \)-terms and one 40 - term that sum to 52).

Step2: Solve for \( y \)

First, subtract 40 from both sides of the equation: \( 3y = 52 - 40 \). Calculating the right - hand side, we get \( 3y = 12 \). Then, divide both sides by 3: \( y=\frac{12}{3}=4 \).

Answer:

\( y = 4 \)
