Which relationships have the same constant of proportionality between yyy and xxx as the equation 3y=27x3y=27x3, y, equals, 27, x?

See Explanation

Step-by-step explanation:

The options are not given; however, the solution is as follows;

Required

Determine relationships with the same constant of proportionality (k)

Divide both sides by 3

The relationship between y, x and k is:

Comparing with ; then

Hence, any of the options with k=9 answers the question.

Take for instance:

Dividing both sides by 2 gives

and hence;

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
