Answer: 
The distance between the coordinates of the two points is measured by the Distance formula
Step-by-step explanation:
The distance between two points P(x1,y1) and Q(x2,y2) is measured by Distance formula i.e Distance=
(x2-x1)²+(y2-y1)²
So, the distance between the two points P(5,-3) and Q(2,4) can be measured by
Distance PQ =
(2-5)²+(4-(-3))²
PQ =
(-3)²+7²
PQ=
9+49
PQ=
58
So,the distance of PQ is 
Thank you for posting your question here at brainly. The answer to the above question is the first one in the choices which is 15. Below is the solution:
<span>
3x + 10 = 55
Subtract 10 from each side...
3x = 45
Divide by 3...
x = 15</span>
The mean is where you add all the numbers up then divide by the amount of numbers there are so 6 that will give you the mean
The mode is the most occurring number
Put all the numbers in order from smallest to largest the median would be the middle number
I think it’s 17x+10y less or equal to 780
