Answer:
x = 11
1/2 =x
Step-by-step explanation:
1) 2(x - 5) + 7 = x + 8
Distribute
2x-10+7 = x+8
Combine like terms
2x -3 = x+8
Subtract x from each side
2x-x-3 = x+8-8
x -3 = 8
Add 3 to each side
x-3+3 = 8+3
x = 11
2) 5(x - 1) - 6x = -11x
Distribute
5x-5-6x = -11x
Combine like terms
-x-5 = -11
Add x to each side
-x+x -5 = -11x +x
-5 = -10x
Divide each side by -10
-5/-10 = -10x/-10
1/2 =x

Hello!
The formula for finding area of a circle is: π · r²
Diameter is 2x the radius. To find the radius when the diameter is given, divide the diameter by 2.
The diameter is 13. 13 ÷ 2 = 6.5
r = 6.5
6.5² = 6.5 × 6.5 = 42.25
π = 3.14
Multiply 3.14 by 42.25 to get the area
3.14 × 42.25 = 132.665
<em>The area of the circle is 132.665 sq. units, which is the last option.</em>
