Mary made $165 for 11 hours of work. At the same rate, how many hours would she have to work to make $75? hours

5 Hours

Step-by-step explanation:

165/11=$15 an hour

75/15=5 hours

5 Hours

Step-by-step explanation:

First you have to find the unit rate which you would find by doing 165 divided by 11 which would equal 15 dollars per hour. Then you do 75 divided by 15 which is 5 meaning it would take 5 hours to make 75 dollars.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
