Answer:
x=1
Step-by-step explanation:
4 - 5(3- 2x) = -2x + 1
Distribute
4 - 15 +10x = -2x+1
Combine like terms
-11 +10x = -2x+1
Add 2x to each side
-11+10x+2x = -2x+2x +1
-11+12x = 1
Add 11 to each side
-11 +11 + 12x = 11+1
12x = 12
Divide each side by
12x/12 = 12/12
x = 1
Your answer is an ordered pair (2,6)
Answer:
66.3 sq ft
Step-by-step explanation:
Here's the plan: we'll find the area of the circle then subtract the area of the triangle.
Area of circle:
A = pi•r^2
= pi•6^2
= 3.14•36
~= 113.04
Area of triangle:
A = 1/2bh
= 1/2(10.39)(9)
The height is the 6+3 in the image.
~= 46.755
Subtract to find
Area of Shaded:
113.04 - 46.755
= 66.285
Round to nearest tenth.
~= 66.3 sq ft
if you don't have a Unit Circle yet, this is a good time to get one, you can find many online, check maybe in yahoo images, or google images.
Check the picture below.
