Constant proporti
in the ea
of a prop
relation
A straight line passes through the points (0,0) and (1,8). What is an
equation that represents the relationship?
Look at how you could use the constant of proportionality.
The graph of the relationship is a straight line that passes
through the origin. That means the relationship is proportional.
Since the line passes through 1, is the constant of
proportionality.

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
