Question

mth1w algebra challengers on your upcoming test, a challenge similar to one of the following from each level will appear. level 3 challenges balance in the diagram, two equal - armed balances are shown. how many \\( \bigcirc \\) would it take to balance \\( \square \square \square \square \\) (answer: 9) level 4 challengers congruent rectangles five identical rectangles are arranged to form a larger rectangle... algebraic arithmetic two 3 - digit numbers...

Explanation:

Step1: Assume weights

Let weight of circle = $C$, square = $S$.

Step2: Set up equations

First balance: $2S = 3C$ → $S = \frac{3}{2}C$.

Step3: Find circles for 4 squares

4 squares weight: $4S = 4×\frac{3}{2}C = 6C$.

Answer:

6
