Is it possible for you to use a graph when doing Variables?
Answer:
5 Miles
Step-by-step explanation:
5 Miles = 1 Miles = $2 X 5 = $10
1 Person = $1
Therefore 2 People = $1 X 2
P = 2(L + W)
P = 22
L = 2W - 4
22 = 2(2W - 4 + W)
22 = 2(3W - 4)
22 = 6W - 8
22 + 8 = 6W
30 = 6W
30/6 = W
5 = W.....width is 5 cm
L = 2W - 4
L = 2(5) - 4
L = 10 - 4
L = 6....length is 6 cm
D) (10 x 55) + (10 x 55) + (10 x 55) + (10 x 55)
use distributive rule to factor out 55:
55 (10+10+10+10) = 55×40
So chance to get a black pen: 4/10=2/5
Chance to get a red pen: 1/10
Chance for the two happened at the same time
2/5 * 1/10 = 2/50=1/25
I think... I’m not very sure though
