Twice a number is 27 more than half the number. what is the number?

twice a number: 2x

is 27 more than half the number: 1/2x

2x = 1/2x + 27

Isolate the x. Subtract 1/2x from both sides

2x (-1/2x) = 1/2x (-1/2x) + 27

2x - 1/2x = 27

1.5x = 27

Isolate the x. Divide 1.5 from both sides

1.5x/1.5 = 27/1.5

x = 27/1.5

x = 18

18 is the number

hope this helps

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
