Answer:
a) there are three groups here
total cash = $120.50
each group takes = $120.50 / 3
each group have = $40.17
b) Total no of groups = 4
Total cash = $120.50
each group takes = $120.50 / 4
Each group have = $30.13
c) Total group =4
Total cash = $120.50 + $9.50
=$130
each group have = $130 / 4
=$32.5
All we have to do here is to express numbers 40 and 5 in each of equations. Note that first number in brackets is always x coordinate and second number is y coordinate
First equation:
5 = 40*8 false
Second
5 = 5*40 false again
Third:
5 = 40/8 = 5 True
checking for just in case last one:
5 = 40/5 = 8 False
Correct one is C)
Answer:
AB = 7
Step-by-step explanation:
The y-coordinate of point A and B is the same.
Therefore, both points lie on the same horizontal line (y = 2).
So determine the distance between them, subtract the x-coordinate of B from the x-coordinate of A:
AB = 4 - -3 = 4 + 3 = 7
However, to calculate the distance between 2 points, regardless if the points are on a horizontal (or vertical) line, you can always use the distance between 2 points formula that is derived from Pythagoras' Theorem, as follows:
let = point A (4, 2)
let = point B (-3, 2)
using the distance between two points equation:
