Answer:
11/30
Probability fractions.
On a coin we flip heads = 1/2 we can change to equal 10/20.
10/20 + 1/20 + 1/20 = 22/60 = 1+2 unit = 2 value on a 20 side.
We can then reduce.
10/20 + 1/20 +1/20 = 22/60 = 11/30
As decimal we can see this is 0.36
Which means 0.36/1
Answer:
<u>In 3 months</u>
Step-by-step explanation:
Henrik buys at 40 cards/month.
Kharif sells at 20 cards/month, from a starting collection of 180 cards.
At x months, Kharif will have 180-(20 cards/month)(x months)
At x months, Kenrik will have 0 + (40 cards/month)*x {We must assume he starts with 0 cards, since no information is given.]
We want to know the nmonths until Both have the same number, so set their equations equal to each other:
180-(20 cards/month)(x months) = 0 + (40 cards/month)*x
180 = x(40 cards/month + 20 cards/month)
180 = x(60 cards/month)
x = 3 months
In 3 months, both will have 120 cards
Answer: the answer is 3
Step-by-step explanation:
3x2=6 and 18-6=12
1^2=1 and 5-1=4
and finally we just divide 12/4=3
y= -4x and 8x-y=6
what you do is switch the negative y to the other side and move the positive 6 to the other side thus making y=8x-6.
I don't get what those numbers are on the question but the way you solve it is by combining them and putting one y into the other
8x-6=-4x 12x=6 6/12=x .5=x
then you plug in x to find y in whichever equation:
-4x=y -4(.5)=y -2=y
so the final answer would be (.5,-2)
