The orginal price is 72 because 52 plus 20 is 72 which should be the regular original price. if a middle schooler like me can do it im sure you can toooo
KL + LM = KM
2x + 5x = 7
7x = 7
x = 7/7
x = 1
KL = 2x......2(1) = 2
LM = 5x.....5(1) = 5 <====
Answer:
1/12
Step-by-step explanation:
The probability that the number pyramid will land on 3 is 1/4 since it is fair.
The probability of the spinner stopping on blue is 1/3.
Multiplying the probabilities you get 1/4 * 1/3 = 1/12
The probability that Rachel will win the game is: 1/12
Step-by-step explanation:
The number cubes has six sides numbered between 1 to 6. the chances of each number are equally likely
Let S be the sample space
The sample space has 6*6 = 36 outcomes.
Now, Let A be the event that the sum of numbers on both number cubes is 10
A = {(4,6),(5,5), (6,4)
n(A) = 3
The probability that Rachel will win the game is: 1/12
