Step-by-step explanation:
2x+3y=6
subtract 2x from both sides.
3y=6-2x
divide by 3 on all sides.
y=2-2/3x
should be 60 cm if not it's 11
Time = t
<span>vf t = 260 </span>
<span>vp t = 320 </span>
<span>so </span>
<span>260/vf = 320/(vf+15) </span>
<span>320 vf = 260 vf +260(15) </span>
<span>60 vf = 390 </span>
<span>3 vf = 39 </span>
<span>vf = 13 km/hour
