Answer:
10
Step-by-step explanation:
The sum of all the interior angles of a pentagon is 540°
So...
540 = 12x + 7x + 16x+ 9x + 10x
Combine like terms:
540 = 12x + 7x + 16x+ 9x + 10x
540 = 54x
Divide by 54 on both sides:
540 = 54x
/54 /54
10 = x

Answer:
The perimeter of the dog run will use 67.2 feet of fencing.
Step-by-step explanation:
First find how long the width is.
24 * 2/5 = 9.6
The width of the fence is 9.6 feet.
To find the total perimeter, add double the length and width.
24 * 2 = 48
9.6 * 2 = 19.2
48 + 19.2 = 67.2
v = w - 20
move -20 to the other side
sign changes from -20 to +20
to get w by itself
v+20= w-20+20
Answer:
w= v+20 or w= 20+v
