Team Alpha had one fourth as many people as team Beta. After 6 people quit team Beta and 12 people were transferred to team Alph

gregori [183]

Let "a" and "b" represent the numbers of people on teams Alpha and Beta, respectively. The problem statement tells you
a = (1/4)b
b - 6 - 12 = a + 12

The first equation can be rewritten to give an expresion for b:
b = 4a
This can be substituted into the second equation to get
4a -18 = a +12
3a = 30
a = 10

There were originally 10 people on team Alpha.

Darko found the distance between points A(3,-4) and B(-1,3) his work is shown below

fiasKO [112]

We know that in two dimensional co-ordinate geometry, the distance,d, between any two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by the formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We will use the above formula that Darko must have used to find the distance between the two points A(3,-4) and B(-1,3). In this case: $(x_1,y_1)=(3,-4)$ and $(x_2,y_2)=(-1,3)$ .
