-1/5 + 1/2 u = -2/3
-6/30 + 15/30 u = -20/30
+6/30 +6/60
___________________
15/30 u = -14/30
(15/30 u = -14/30) ÷ (15/30)
u = -14/15
u = -.933
Answer:
23 marbles
Step-by-step explanation:
Number of children = 10
Number of marbles = 180
Since Betsy gets the most and no 2 children gets the same number of marbles
The least number of marbles Betsy could get will be x ; with the other 9 children receiving 1 less each
That is :
Betsy = x
9th child = x - 1
8th child = x - 2,... 1st child = x - 9
Hence,
(x + x - 1 + x - 2 + x - 3 + x - 4 + x - 5 + x - 6 + x - 7 + x - 8 + x - 9) = 180
10x - 45 = 180
10x = 180 + 45
x = 225 / 10
x = 22.5
x = 23
Hence, the least Betsy could get is 23 marbles
Answer:
N = -5
Step-by-step explanation:
Move the decimal point right until it is right after the first significant figure.
N = 5
But wait! It's a decimal so it has to be negative.
N = -5
That is a false statement the coin has two sides one with a head and a tail’s it will always be a 50 out of 100 chance that it will land on heads or tails so basically FALSE
Answer:
• Assume Q is a mid point of line MY
