There were 45 markers originally in each box.
Step-by-step explanation:
Given,
Boxes ordered = 3 large boxes
Markers given to one teacher = 15
Markers given to 3 teachers = 15*3 = 45 markers
Remaining markers = 90
Let,
x be the original number of markers in 3 boxes.
Total markers - markers given to teachers = markers left
There were 135 markers in 3 boxes.
3 boxes = 135 markers
1 box =

Nothing much to say about this problem. There are 38 spaces on the roulette wheel and an every space on a fair wheel has an equal probability of being selected. So you would expect 1/38 = 0.026315789 = 2.6315789% of the time for the number 21 to show up.
Answer:
-y = 2x-3
Step-by-step explanation:
This is because as last step if 2y is divided by 2 then we would apply same each side to make -4x-6 become -2x -3
Three geometric means between 3 and 48 are 6, 12 and 24.
W=rectangle width
2w+1=rectangle length
w(2w+1)=210
2w²+w-210=0
(2w+21 )(w-10)=0
w=-21/2 or 10
