The expression represents the total number of points Mona will earn if she catches x fish, y octopus, and z crabs is 30x + 80y - 15z.
<h3>What is an expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given to us
30 points for fish
80 points for Octopus
-15 points for crab
As it is given in the problem that Mona catches x number of fishes, y number of octopuses, and z number of cabs. therefore,
Points earned through fishes ![=x \times 30 = 30 x](https://tex.z-dn.net/?f=%3Dx%20%5Ctimes%2030%20%3D%2030%20x)
Points earned through Octopus ![=y \times 80 = 80 y](https://tex.z-dn.net/?f=%3Dy%20%5Ctimes%2080%20%3D%2080%20y)
Points earned through crabs![=z \times -15= -15 z](https://tex.z-dn.net/?f=%3Dz%20%5Ctimes%20-15%3D%20-15%20z)
Total points earned by Mona in the video game
= Points earned through fishes, octopus, and crabs
![=30x + 80 y -15z](https://tex.z-dn.net/?f=%3D30x%20%2B%2080%20y%20-15z)
Hence, the expression represents the total number of points Mona will earn if she catches x fish, y octopi, and z crabs is 30x + 80y - 15z.

There are 6^3 = 216 possible outcomes of rolling these 3 dice. Let's count the number of possible rolls that meet the criteria b < y < r, manually.
r = 1 or 2 is obviously impossible. So let's look at r = 3 through 6.
r = 3, y = 2, b = 1 is the only possibility for r=3. So n = 1
r = 4, y = 3, b = {1,2}, so n = 1 + 2 = 3
r = 4, y = 2, b = 1, so n = 3 + 1 = 4
r = 5, y = 4, b = {1,2,3}, so n = 4 + 3 = 7
r = 5, y = 3, b = {1,2}, so n = 7 + 2 = 9
r = 5, y = 2, b = 1, so n = 9 + 1 = 10
And I see a pattern, for the most restrictive r, there is 1 possibility. For the next most restrictive, there's 2+1 = 3 possibilities. Then the next one is 3+2+1
= 6 possibilities. So for r = 6, there should be 4+3+2+1 = 10 possibilities.
Let's see
r = 6, y = 5, b = {4,3,2,1}, so n = 10 + 4 = 14
r = 6, y = 4, b = {3,2,1}, so n = 14 + 3 = 17
r = 6, y = 3, b = {2,1}, so n = 17 + 2 = 19
r = 6, y = 2, b = 1, so n = 19 + 1 = 20
And the pattern holds. So there are 20 possible rolls that meet the desired criteria out of 216 possible rolls. So 20/216 = 5/54.
AB and CD are parallel because when 2 lines in a plane are parallel it means they do not intersect
0.5 times 100 = 50... 50 is your answer
Hello again, hehelol12.
PQ is equal to CB. So the length of PQ must be 9.
Angle PQR is equal to CBA. Therefore the measure of angle PQR is 46.
I hope this helps!
