A cat is measured by millimeters, feet, inches
3x-12 is simplified from parenthesis
Sorry I was wrong, I didn’t mean to get it wrong.
The answer is: 1.25x + 1.75
Let the weight of the first truck be represented by w.
total weight = w + (2 + w) + (2 + 2 + w) + (2 + 2 + 2 + w)
32 = 4w + 12
20 = 4w
w = 5
Therefore, the first truck weighs 5 tons, the second weighs 7 tons, the third weighs 9 tons and the fourth weighs 11 tons.
