-2/3x +1/3 +x = 2/5
⇒ 1/3x + 1/3 = 2/5
⇒ 1/3x = 2/5 -1/3
⇒ x/3 = 1/15
⇒ 15x = 3
⇒ x = 3/15
⇒ x = 1/5
Answer:
x = 12
consider this a straight line:
A B C
-------------------------------------------------
<u>solve for AB</u>:
⇒ AB = AC - BC
⇒ AB = 2x - 7 - ( x - 3 )
⇒ AB = 2x - x - 7 + 3
⇒ AB = x - 4
<u>solve for x</u>:
⇒ x - 4 = 8
⇒ x = 8 + 4
⇒ x = 12
Answer: 3.25%
Step-by-step explanation:
Answer is 1/36...
probability of rolling a 3 is 1/6 so if you do it twice it will be 1/6×1/6=1/36
