1:00 to 2:15 is 1 hour and 15 minutes.
In that time the duck went from 50 to 125, which is a 75 degree increase.
75 degrees / 75 minutes = 1 degree per minute increase.
175 degrees - 125 degrees = 50 degree more it needs.
1 degree per minute x 50 degrees = 50 more minutes.
50 minutes after 2:15, would be 3:05
It will be 175 degrees at 3:05
Point slope form
y-y1=m(x-x1)
slope=m
a point is (x1,y1)
slope=(y2-y1)/(x2-x1)
given
(-6,4) and (2,0)
slope=(0-4)/(2-(-6))=-4/(2+6)=-4/8=-1/2
a point is (-6,4)
x1=-6
y1=4
y-4=-1/2(x+6)

So you know that:
2x+y=14+y
and
5x-y=x+13y
Here you have two equations with two unknown variables:
If you isolate x from the second equations you get:
x=(7/2)y
Insert that in the first equations and solve for y:
2*(7/2)y+y=14+y
y=2
Insert that value for y in one of the two equations (i chose the first):
2x+2=14+2
x=7
Therefore x=7
Hope that helped.
Actually you could start with isolating x, and then insert that in one of the two equations.

You need to isolate p:
1.4 divided by 0.7 = 0.7p divided by 0.7 (this eliminates 0.7)
2 = p
