Find the constant of proportionality for the table and write in the form y = kx. a) y = 1 4 x b) y = 4x c) y = 6x d) y = 24x

Option 'B' is correct.

Explanation:

Since we have given that

Number of lemons used is denoted by 'y'.

Number of glasses of lemonade is denoted by 'x'.

As we can observe that ,

So, if write it in the form y=kx,

It will be y=4x.

Hence, Option 'B' is correct.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
