The 9 combinations that exist for two movements:
R,R
R,L
R,U *
L,R
L,L
L,U
U,R *
U,L
U,U
Walker would only be able to make it to (1,1) with only 2 of these combinations.
So if he were only allowed to make two movements, his chances of arriving at (1,1) would be 2/9.
Answer:
<u>The number is 170</u>
Step-by-step explanation:
Let's solve for x, this way:
x = A number that decreased by 20% of itself, the result is 136
20% = 0.2
x - 0.2x = 136 (Like terms)
0.8x = 136
x = 136/0.8 (Dividing by 0.8 at both sides)
x = 170
Let's prove that x = 170 is correct
170 - 0.2 (170) = 136
170 - 34 = 136
136 = 136
We proved that x = 170 is correct
