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
Hope this helps :)
Answer:
x=6
Step-by-step explanation:
3x-7=5x-19
12=2x
x=6
Answer:
║x - 175,000║≤ 20,000
Step-by-step explanation:
Let x be the amount the Fraziers are willing to pay. Since the house costs $175,000 and they are willing to deviate from this price no more than $20,000, so x = $175,000 ± $20,000.
So, x - 175,000 = ± 20000
║x - 175,000║= 20,000
But we require
║x - 175,000║≤ 20,000
which is our required open sentence.
The perimeter of the polygon will be given by:
Perimeter=distance around the figure
Thus the perimeter will be:
P=9.9+(9.9-5.9)+5.9+15.9+(15.9-4.6)+4.6
P=9.9+4+5.9+15.9+11.3+4.6
P=51.6
Answer: 51.6 units
