Step-by-step explanation:
Look at where the lines intersect each other, if they do then you can use one of the coordinates. the lines that don’t touch means no solution
Set up multiplication/division of proportions to cancel out units that you don't want and to introduce units that you do want in your final solution...
2678cm(in/2.54cm)(ft/12in)=2678/30.48 ft≈87.86 ft (to nearest hundredth)
Ooh, scary math
n+2b=67.5
n=27
27+2b=67.5
minus 27 both sides
2b=40.50
divide both sides by 2
b=20.25
