First, we have got to make all terms like terms by changing 10 into a fraction. 10=10/1.
Now you multiply: 3 x 10 Make sure that you multiply straight across.
5 1
After multiplying, you get 30/5.
To finish, all you have to do is divide and get 6.
Answer:

x=5.1 , 1.4
Step-by-step explanation:
use quadratic equation
Answer:
The coordinates of the point S = (12, -22)
Step-by-step explanation:
The coordinate points of T = (0,6)
Mid point of ST = (6,-8)
Let the coordinates of S = (a,b)
Now, BY MID POINT FORMULA:
If (x, y) and (z, w) are the line point joining line segment and (p,q) is the coordinate of mid point. Then

So, here similarly, 
⇒ 
⇒ a =2 x 6 = 12, b = 2 (-8) -6 = -22
⇒(a,b) = (12, -22)
Hence, the coordinates of the point S = (12, -22)
