Let the weight of triangle be x units. You are given that the weight of square is 1 unit.
1) On the left side of the balanced beam you can see 3 triangles and 5 squares. The weight on left side is 3·x+5·1=3x+5 units.
2) On the right side of the balanced beam you can see 2 triangles and 7 squares. The weight on right side is 2·x+7·1=2x+7 units.
3) If the whole system is balanced, then the weights on left and right sides are equal:
3x+5=2x+7.
Solve this equation:
3x-2x=7-5,
x=2 units.

Answer: 5
Step-by-step explanation:
Distance between two points is calculated as:
Step 1: locate the coordinate points:
Point 1- (x1,y2) = (-5, -2)
Point 2-(x2,y2)= (-9, -5)
Formula to find distance between two points = √(x2−x1)2 + (y2−y1)2
Step 2: input the values
√(−9− −5)2 + (−5− −2)2
= √(−4)2 + (−3)2
=√16 + 9
= √25 ........ square root of 25
= 5
Distance between points (-5, -2) and (-9, -5) is 5
