Answer:
1km=1000m 160m=0.160x4=0.64
Step-by-step explanation:
Ifl = 160m, then:
P = 4 * 160m\\P = 640m
Thus, the perimeter of the base of the pyramid is 640m.
On the other hand, by definition: 1Km = 1000m
By making a rule of three we have:
1Km ---------> 1000m
x --------------> 640m
Where "x" represents the perimeter of the base of the pyramid in Km.
x = \frac {640 * 1} {1000}\\x = 0.64km
Answer:
3x + 9 = 21
Step-by-step explanation:
Let Henry's age be x
Mary's age = 9 + 3x
21 = 9 + 3x
Can also be written as 3x + 9 = 21
