Nina ran 12 4/5 laps in 1/4 of an hour . at this rate , how many laps could she run in a hour ?

Explanation:

Since we have given that

Number of laps Nina ran is given by

Time taken by Nina to ran the lap is given by

Now, we use the unitary method ,

Now, we change it into mixed fraction,

Hence,

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
