Answer:
y = 2/3
Step-by-step explanation:
Assuming you are looking for "y":
15 * ( y - 4 ) - 2 * (y - 9 ) + 5 * (y + 6) = 0
15y - 60 - 2y + 18 + 5y + 30 = 0
15y - 2y + 5y -60 + 18 + 30 = 0
18y = 60 - 18 - 30
18y = 12
y = 12/18
y = 2/3
Answer:
probability for 3 on a dice (P3) in one dice =

probability for even no. of a dice (Pe) =

Therefore, the probability of finding 3 on one dice and even on another (P) = P3 + Pe

Set a proportion. They are similar triangles.
Volume = 3.5×3.5×5 = 61.25 inches. A. is the correct answer
