Answer:
A triangular prism has 5 faces (3 rectangular and 2 triangular), 9 vertices and 6 edges.
Answer:
absolute value its written as:
| expression | > x
*> written can also be < , ≥ , or ≤
| | (two vertical lines on both sides of something) indicate absolute value
(absolute value considers the space between a number and 0;
| x | = 3
then x could be = 3 or = -3
you can also think of anything inside | | to be written as positive;
| 3 | = 3
| -3 | = 3)
you could also right, from this example: | x | > 3
our value of x could either be greater than 3, or, our x-value is negative (and only the absolute value is greater than 3, meaning that negative -x, is greater than three)
we separate these possibilities into two expressions:
x > 3 - x > 3
· -1 · -1 {inequalities flip direction when multiply by negative}
x < -3
so, x > 3 and x < -3 can be combined:
x > 3 <em>or </em> x < 3

hope this helps!!
3x - 1 = 5x - 11
Add 1 to both sides.
3x = 5x - 10
Subtract 5x from both sides.
-2x = -10
Divide by -2.
x = 5
QPR = 1/2 (31 + 98)
Angle QPR = 64.5 degrees
If you're asking how many pies must be sold to get enough money back, the answer is 37, and that is because 62.84 + 65.25 = 128.09 / 3.50 = 36.59, but you can't buy 0.59 of a pie, so you round it up and get the answer of 37 slices.
