Answer:

The answer would be A.) 111

Step-by-step explanation:

Two times a number plus 3 equals one half of the number plus 30. What is the number please?
Zanzabum

Answer:

Step-by-step explanation:

2*x + 3 = 1/2x + 30             Subtract 3 from both sides

<u>       - 3                -3</u>

2x = 1/2x + 27                     Subtract 1/2 x from both sides

<u>1/2 x  -1/2 x</u>

1 1/2 x = 27                         change 1 1/2 to 3/2

3/2 x = 27                           Multiply by 2/3

2/3 * 3/2x = 27 * 2/3

x = 18

Area = 1/2*a*P
(a = apothem , P= Perimeter)
P = Sum of all sides
   = 12*8
   = 96
Area = 1/2*30*96 = 1440

Hope this helps!

Since they are going in opposite direction,

The time will be 3:30 PM + 1 hour 30 min = 5 :00 PM
