Answer:
Perimeter = 15 cm
Step-by-step explanation:
The equation P=5s represents the perimeter P of a regular pentagon with side length s.
We need to find the perimeter of a regular pentagon with side length of 3 cm.
To find it, put s = 3 cm in the given equation.
P = 5(3) cm
= 15 cm
Hence, the perimeter of the regular pentagon of side length 3 cm is 15 cm.
Answer:
5
Step-by-step explanation:
-4w+7=-10w+37
+10w +10w
=============
6w+ 7=37
-7 -7
==========
6w=30
/6 /6
w=5
Answer:
2/3 ( 3x - 4 ) + 3x = 5/6
2x - 8/3 + 3x = 5/6
5x - 8/3 = 5/6
6(5x -8/3) = 6x5/6
30x - 16 = 5
<u> +16 +16</u>
<u>30x = 21</u>
30
x = 21/30
x = 0.7
Step-by-step explanation:
- distribute the bracket by 2/3
- combine like-terms
- multiply both sides by 6 (lcm of 3 and 6)
- add 16 to both sides
- divide both sides by 30 to get x
