Step-by-step explanation:
Share 20pounds in the ratio 2:3
Total ratio=2+3=5
2/5×20=8
20-8=12
Sharing 20pounds in that ratio gives 8pounds:12pounds
Share 15cm in the ratio 1:3
Total ratio=1+4=4
¼×15=3.75
15-3.75=11.25
Sharing 15cm in that ratio gives 3.75:11.25
Answer:

The answer is

Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To write an equation of a line given a point and slope we have
y - y1 = m( x - x1)
where (x1 , y1 ) is the point and m is the slope
Equation of the line using point P(3 , 5) and m = 2/3 is



We have the final answer as
