Tanya is wrapping a gift. she is using a piece of red ribbon that is 11/12 foot long and blue ribbon that is 5/6 foot long. how much ribbon does she use in all to wrap her hift

Step-by-step explanation:

Tanya is is using both red and blue ribbons to wrap a gift. The length of the piece of red ribbon that she is using is 11/12 foot long.

The length of the piece of blue ribbon that she is using is 5/6 foot long.

The total length of ribbon that she will use in all to wrap her gift would be the sum of of the length of red ribbons + sum of the length of the blue ribbon. It becomes,

11/12 +/5/6 = (11 + 10)/12 = 21/12 foot

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.
