Answer:
k-l= 7 -3
6 0
Step-by-step explanation:
k-l=13 7 - 6 10
25 18 19 18
= 13-6 7-10
25-19 18-18
= 7 -3
6 0
Since we have a 37-gon here, the sum of the interior angles will be:
<span>(37 - 2) * 180 </span>
<span>= 6300 degrees</span>
S+B=47.5
S-15.50=B
so subtitute S-15.5 into the first equation and get
S+(S-15.5)=47.5 or
2S-15.5=47.5
add 15.5 to both sides and get
2S=64
divide both sides by 2 and get
Sarah spent 32 dollars
Bryan spend 32-15.5=16.5
