The formula of average speed is distance/time. So 623/6= 103.833333 repeatings let just put it around 103.84km/s^2
a. 6 x 5 = 30
b. 5.6 x 5 = 28
a. 20 devided by 5 = 5.6
b. 36 devided by 5 = 7.2 (i dont know, that sounds like a pretty tall person to me)

Step-by-step explanation:
the formula of coordinates (x, y) that reflected across the x-axis : (x, y) => (x, -y)
so,
A(3, -2) => A'(3, 2)
B(5, 5) => B'(5, -5)
C(-4, 2) => C'(-4, -2)
23x-13=2(x+2)
First you would distribute the 2 into the parenthesis
It will look like this after: 23x-13=2x+4
Then you would subtract 2x on both sides because u have to get the x's on one side
It will look like this after:21x-13=4
Then you would add 13 to both sides
It will look like this after: 21x=17
Then you would divide 21 on both sides
Your final product is 21/17
