Answer:
18.03
Step-by-step explanation:
So first David went 200m west. I drew a line that went to the west. Next he went 125m north. I drew a line that went north. The question is asking you how far away he is from his starting point. I drew a triangle and connected those two points from where he began. So to find the length or missing side, you need to use an equation known as the pathaegorean theorem. A²+ B²+ C². 125+200 is 325. The square root of 325 is 18.0277. However, they ask us to round to the nearest hundredth. So that number would you round to 18.03 ( since the seven makes the two go up).
Based on the given parameters, the value of Rx is R18
<h3>How to determine the value of Rx?</h3>
The given parameters are:
Number of people = 25
Amount paid = Rx
Additional people of 5 = Amount paid being R3 less
The total amount paid is calculated using:
Total amount = Number of people * Amount paid
Substitute the known values in the above equation
Total amount = 25 * x
Total amount = (25 + 5) * (x - 3)
Substitute Total amount = (25 + 5) * (x - 3) in Total amount = 25 * x
(25 + 5) * (x - 3) = 25 * x
Evaluate the sum
30 * (x - 3) = 25 * x
Evaluate the products
30x - 90 = 25x
Collect like terms
30x - 25x = 90
Evaluate the like terms
5x = 90
Divide both sides by 5
x = 18
Hence, the value of Rx is R18

Answer:
5
5.7
7.1
6.9
Step-by-step explanation:
|4 - 9| = 5
|-3.1 + 8.8| = 5.7
|-7.1| = 7.1
|2.7 + 4.2| = 6.9
