Not sure if you are just looking for equations but it would be written as
1/4(r+10)=r-4
Solving would be
1/4r+10/4=r-4
26/4=3/4r
r=26/3 or 8.66
Use A: to find the value of x. In order to find that you would have to match one part of the proportion. x should be the numerator over 15 and 12 should be over 20 (The total length of that side of the triangle). Good luck. : )
<span>17−2p=4p+5
Add 2p to both sides
17=6p+5
Subtract 5 from both sides
12=6p
Divide 6 on both sides
Final Answer: 2=p</span>
