Translate the equation and solve: Two times the difference of a number and 9 is 12. *
O 2x - 9 = 12; x = 10.5
0 2x - 9 = 12; x = 15
2(x - 9) = 12; x = 1.5
2(x - 9) = 12; x = 15

2(x-9) = 12; x = 15

Step-by-step explanation:

Have a nice day

Jenny will knit 8 inches per each hour.

Step-by-step explanation:

First I know that 1 foot is 12 inches.

1/3 of 13 is 4.

1 hour is 60 minutes.

2/3 of 60 is 40.

so she knits 4 inches in 40 minutes.

We will now add 1/3 to both to see how many inches/feet she knits per hour/60 minutes.

Adding 1/3 to 2/3 of an hour will look like:

That equals 60/60 which is 1 hour.

Adding 1/3 to 1/3 of a foot will look like:

That equals 8/12, which is 8 inches in a foot.

This means that in one hour, Jenny will knit 8 inches of a foot.
