When side changes positive changes into negative.
Answer:
-2
Step-by-step explanation:
3 - 5 = -2
Place the dot on -2 on the number line that is on your problem as the answer. To show the steps on the number line, use your jumps to go back. For example, your starting point will be on 3, and then use your jumps to go back by 5; that means you go into the negatives. For this case, it is -2.
Assuming that the sides of the box are square (having 90° angles on all four corners), then it should be relatively easy for us to find the length of the box, given the perimeter and the length of one side.
We know the length of all sides combined is 42 inches, and that the length of one side is 9 inches. With a rectangular prism, the length of one side is the same as the length of the opposite side, so there are two sides that measure 9 inches.
All we need to do to find the measure of both the other sides' lengths is subtract the known lengths from the total length.
9 + 9 = 18
42 - 18 = 24
So the rest of the side lengths added together is 24 inches.
There are two sides left, so all we have to do is divide by 2 to find the length of the box.
24 / 2 = 12
The length of Kate's jewelry box is 12 inches.

Answer:
65 degrees
Step-by-step explanation:
First, solve for the unknown angle( not the y's).
the angle 130 is supplementary to that angle so we will use an equation to solve it. (supplementary means it adds up to 180 degrees)
x+130=180
-130 -130
x = 50 so, 50 is the measure of the interior angle
Now we have to use another equation to solve for y:
50+2y=180
-50 -50
2y = 130
/2 /2
y = 65
Thus, y is 65
