Answer:
19 units
Step-by-step explanation:
A regular polygon has equal-length sides. This fact can be used to solve for the value of x, and for the side length. Knowing the side length, we can find the perimeter.
__
<h3>side length</h3>
5 -2x = 4x +9 . . . . . marked sides are the same length
-4 = 6x . . . . . add 2x -9
-2/3 = x . . . . . divide by 6
5 -2(-2/3) = 5 +4/3 = 6 1/3 . . . . length of one side
<h3>perimeter</h3>
The perimeter is the sum of the side lengths, or 3 times the length of one side.
P = 3s = 3(6 1/3)
P = 19 . . . . units
The perimeter of the polygon is 19 units.
Answer:
113 min
Step-by-step explanation:
10s =====> 36 bottle caps
X ======> 24 408 bottle caps
X = (24 408 × 10) / 36
X = 678 ×10 =6780 sec
1 min = 60 sec
? min = 6780 sec
= 6780 ÷ 60
= 113 min
So in 113 min 24 408 bottle caps can be fixed
113.5
Step-by-step explanation:
454g / 32G = 14.1875 x 8 = 113.5
Answer:
(8x^9 x y^4) : (1/2x^3)=16x^6y^4
Step-by-step explanation:
8 : 1/2 = 16
x^9 : x^3 = x^6
