10.79/1200=.009
.009*1200=10.79 this is a double check to make sure our price per square foot is correct.
.009*4000=$36.00
It will cost $36.00 to seed the 4,000 square feet at that price.
Answer:
x=56 and the exterior angle is 116
Step-by-step explanation:
We will call the unknown angle in the triangle y. Angle y and the angle (2x +4) form a straight line so they make 180 degrees.
y + 2x+4 =180
Solve for y by subtracting 2x+4 from each side.
y + 2x+4 - (2x+4) =180 - (2x+4)
y = 180-2x-4
y = 176-2x
The three angles of a triangle add to 180 degrees
x+ y+ 60 = 180
x+ (176-2x)+60 = 180
Combine like terms
-x +236=180
Subtract 236 from each side
-x+236-236 = 180-236
-x = -56
Multiply each side by -1
-1*-x = -56*-1
x=56
The exterior angle is 2x+4. Substitute x=56 into the equation.
2(56)+4
112+4
116
Midpoint formula: (x1+x2/2 , y1+y2/2)
So, (-1+3/2 , 9+8/2)
-2/2 = -1 17/2 = 8.5
Answer: (-1,8.5)
