1/4! Because there would be three left. Aka 3/12. Simplification.
Alright, first blank one is 1/3, then 2/3, then 1, then 1 1/3, then 1 2/3.
Now, shade the 1/3 and 2/3 in blue. Shade the 0, 1 and 2 in red.
Shade the 1 1/3 and 1 2/3 in yellow.
Glad I could help, and good luck!
6/x = x-1
Multiply x by both sides
6= x(x-1)
Set x and x-1 equal to 6
x = 6, x = 1+6 = 7
14-4x=2y divide 2 to both sides
VVVVV
7-2x=y you will need this on the next step
-----------------------------------------------------
y+2x=7
y=7-2x
(7-2x)+2x=7 -------> 7-2x+2x=7
7=7
The answer is C.
If the perimeter is 9 inches, each side is 3 inches.
The height of an equilateral triangle splits the triangle in two right sub-triangles: for example, consider a triangle ABC and the height AH starting from A, perpendicular to BC.
The triangle AHC is a right triangle, whose legs are AH and HC, and whose hypotenuse is AC.
AH is half the side, and AC is a side. So, we can use the Pythagorean theorem to find the height:

So, the area is
