Think of the metric system like this: K H D B D C M
Now. you have kilo at the begining and milli at the end. To transition from left to right you multiply by 10 each time. To transition from right to left, you divide by 10 each time.

Answer:
60
Step-by-step explanation:
Let m represent the mark Cheryn scored on her first quiz. Then her average is ...
(m +76 +89)/3 ≥ 75
m +165 ≥ 225 . . . . . . . . multiply by 3
m ≥ 60 . . . . . . . . . . . . subtract 165
Cheryn scored a minimum of 60 marks on her first quiz.
Step-by-step explanation:
2x^2+6x=36
x^2+3x=12
x^2+3x-12=0
x=(-3+(57)^0.5)/2 or x=(-3-(57)^0.5)/2
Divide 85 and 19.
85/19= 4.417....
So, we know that each student can’t have above 4. But, if each student has 4 grapes, 19x4 = 76.
85-76=9
There are 9 grapes left over.
If there are 5 people, they get 3 cans.
We want to give the same amount of soup to everyone, so if there are twice as many people, we're going to need twice as much soup.
(10 people, 6 cans)
Now say we had 20 people. (4 times as many)
We'd use 4 times as many cans soup, which would be 3×4 = 12 cans.
So it seems tht both B and D are correct.
