Question

The quantities xxx and yyy are proportional.

Answer 1

Answer:

Therefore the constant of proportional is r=7.

Step-by-step explanation:

The quantities x and y are proportional.

      x                y

i)     2              14

ii)    6               42

iii)   11               77

Since x and y are proportional.

y= rx

(i)

Now plug y= 14 and x=2

14=r.2

$\Rightarrow r=\frac{14}{2}$

$\Rightarrow r=7$

(ii)

Now plug y= 42 and x=6

42=r.6

$\Rightarrow r=\frac{42}{6}$

$\Rightarrow r=7$

(iii)

Now plug y=11 and x=77

77=r.11

$\Rightarrow r=\frac{77}{11}$

$\Rightarrow r=7$    

Therefore the constant of proportional is r=7.
