the coordinate of X is at 8 units of P and at 4 units to the left of Q
So the coordinate of X is: -5 + 8 = 3
How to find the coordinates of point x?
We know that point X is between points P and Q, in such a way that the ratio between the lengths of the segments PX and XQ is 2:1
First, we can length of the segment PQ is equal to the difference between their coordinates, so we get:
L = 7 - (-5) = 12
Then the length of segment PQ is 12 units, if we divide that in 3 we will get:
12/3 = 4 units.
So the segment PQ can be divided into 3 segments of 4 units each.
If the ratio PX to XQ is 2:1
Then the segment PQ must be divided into 3 parts, such that PX takes two of these parts and XQ is the remaining one.
Then the coordinate of X is at 8 units of P and at 4 units to the left of Q
So the coordinate of X is: -5 + 8 = 3

A and B are vertical angles. If mA = (3x +22)° and m/B= (7x – 22)°,
then find the value of x.
Answers
Answer:
x = 11
Step-by-step explanation:
If given angles m∠A = (3x +22)° and m∠B= (7x – 22)°, the value of x is 11.
Vertical angles are formed by the intersection of two lines. They are opposite to each other and have equal measures. In this case, we have two vertical angles, ∠A and ∠B.
Given that m∠A = (3x + 22)° and m∠B = (7x - 22)°, we can set up an equation based on the fact that vertical angles are equal.
(3x + 22)° = (7x - 22)°
To solve for x, we can simplify the equation:
3x + 22 = 7x - 22
Next, we can isolate the variable x by moving the terms containing x to one side of the equation:
3x - 7x = -22 - 22
-4x = -44
Finally, we divide both sides of the equation by -4 to solve for x:
x = -44 / -4
x = 11

Number of unshaded squares = 3x.
This is due to the fact that there are 3 times as many unshaded squares as there are shaded squares (2 times more unshaded = 3*). (shaded)
Overall, there are 40 squares (5 * 8), therefore 40 total squares—shaded and unshaded—are present.

Bruno’s burgers has a cook to server ratio of 2:5, total number of servers & cooks is 42, how many more servers does Bruno’s burgers employ than cooks
Answers
There are 18 more servers than cooks at Bruno's burgers when the ratio is 2 : 5.
We are given that the ratio of cook to server in Bruno's Burgers is given by 2 : 5
We also know that the total number of cooks and servers = 42
Now, let number of cooks be 2 x and the number of servers be 5 x
So, ATQ, we get that:
2 x + 5 x = 42
7 x = 42
x = 42 / 7
x = 6
Number of cooks = 2 x = 2 (6) = 12
Number of servers = 5 x = 5 (6) = 30.
Difference = 30 - 12 = 18
Therefore, we get that, there are 18 more servers than cooks at Bruno's burgers when the ratio is given as 2 : 5.

Reroll 6’s = 26 times
Failed turn on 6's = 21 times
If the initial roll is a 6, the question enters an unending cycle. Reroll till it isn't 6, or simply treat it as a failed round since the roll was legal and didn't result in a pair of twos.
The likelihood of each number being rolled is the same.
If the first roll is n, there are (6 - n) options for the greater number. Thus p = 1/(6 - n) for a specific (possible) result such as n + 2.
Then,
p(2 apart) = p(1, then 3) + p(2, then 4) + p(3, then 5) + p(4, then 6)
Reroll 6’s:
p(2 apart) = (1/5)(1/5) + (1/5)(1/4) + (1/5)(1/3) + (1/5)(1/2)
p(2 apart) = (1/5)(1/5 + 1/4 + 1/3 + 1/2) = 0.25666…
So for 100 times, we will get 26 times 2 apart
Failed turn on 6:
p(2 apart) = (1/6)(1/5) + (1/6)(1/4) + (1/6)(1/3) + (1/6)(1/2)
p(2 apart) = (1/6)(1/5 + 1/4 + 1/3 + 1/2) = 0.2138
So for 100 times, we will get 21 times 2 apart
