Answer» Answer: p=(25/7) substitute into second equation. {5/(sqrt 7/5)}=p sqrt (7) INVERT and multiply (25/sqrt (7))=p (sqrt (7)) multiply both sides by sqrt (7) 25 =7p divide by 7 (25/7)=p Check sqrt (7)=2.65 x=2.65/5, or 0.53 5/0.53 is 9.45 (25/7)*2.65=9.46 This is the same given that sqrt (7) is being ROUNDED. |
