Solving Equations with Variables on Both Sides A builder wants to build the cross section of a bridge shown in the diagram.
55 ft 4 in
I-Beam
Description of Diagram Specs:
• The cross section is 55 ft 4 in. wide.
• The distance between each end of the bridge to the first l-beam is 3 ft.
• The thickness of each web of the I-beam is ft.
.
• The distance between each I-beam is b.
1. An equation to find the distance b between each beam is
2. The approximate distance b between each consecutive pair of I-beams is
