……….Yes it is true that trapezoid is a polygon that has two bases
27/7 or Decimal: 3.857143
The reference angle is
pi/3.
At 180 it would be 9pi/3 so going past that is 10pi/3.
D, 495.
9 x 55 = 495, so nine containers can hold 495 balls.
You need to isolate the variables. For the first equation add x to both sides, which leaves you with y.
For the second equation, divide each side by 2 leaving you with
x= 6+y. Subtract y from each side. Subtract x from both sides. Now you have y= x + 6.
Now graph those equations.
