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

answer: x=60

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
