Mathematics
1 answer:
romanna [79]2 years ago
3 0

Answer:

The line going to the left aka the negative side!

X < -15 means X is less than -15

The line's purpose is to to show the possibilities of X.

So all the numbers lower than -15 are all possibilities of X. (Example: -16, -17 or -20 would be a possibilty of X because they are less than -15!)

Anything going above -15 is not a possibility of X (Example: -14, -13, or 2 are not possibilities of X as they are greater than -15!)

Jenna uses 18 inches of ribbion for each box she wraps how many yards of rib ion does she need to wrap 4 boxes
Sav [38]
Hello Myeisha91! 

First we need to find how many inches in total to wrap 4 boxes. We do that by multiplying 18 x 4 = 72 so Jena needs 72 inches. The question wants to know how many yards so we need to convert 72 inches into yards. We can convert inches to yards by using a conversion factor. We know that 1 inch = 0.0277778 yd. Now that we know  1 inch = 0.0277778 yd, lets convert the 72 inches to yards.

We convert 72 in to yards by multiplying 72 in by \frac{0.0277778\;yd}{1\; in}
72\;in\times\frac{0.0277778\; yd}{1\;in} = 2\; yd
So Jenna will need 2 yards to wrap 4 boxes.
