Jeremy's teacher buys 6 packs of thumbtacks. Each pack contains t thumbtacks. She uses 18 thumbtacks to display posters around her classroom. Which expression gives the number of
thumbtacks she has left?
A) 3(6-t)
B) 3(t-6)
C) 6(t-3)
D) 6(3-t)

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
