Answer: 3 red bricks and 4 grey bricks
<u>Step-by-step explanation:</u>
You have 17 kg total with weights of 3 kg and 2 kg.
Since 17 is an odd number, subtract one 3 kg weight to get an even #.
17 - 1(3 kg) = 14
14 ÷ 2 kg = 7
One 3 kg weight results in seven 2 kg weights = 8 total weights.
Since the given problem states that there are only seven weights, my guess was not correct.
Try Again:
Since we need and odd number of 3 kg weights, try three 3 kg weights
17 - 3(3 kg) = 8
8 ÷ 2 kg = 4
Three 3 kg weights and four 2 kg weights = 7 total weights.
Note that this can be solved mathematically using a system of equations:
Weight: 3r + 2g = 17
Quantity: r + g = 7
