Answer:
30/169
Step-by-step explanation:
We need to know how many marbles in the bag
6 red marbles + 2 white marbles + 5 blue marbles = 13 marbles
P (red) = red / total = 6/13
We then put the marble bad so there are still 13 marbles in the bag
P(blue) = blue /total = 5/13
P (red then blue ) = P(red) *P(blue)
= 6/13 * 5/13 = 30/169
379500 would be the population after 10 years
We need to divide 64/3 by the book thickness, 4/3. Since these two fractions have the same denominator, we can drop the 3's and focus on 64/4.
64/4 = 16
The third answer is the correct one. The other three answers aren't even close!
<u>The answer is A. Multiply both sides of the top equation by 2</u>
So since we know that 4 × 2 = 8, it would only make sense to multiply both sides by 2 so that the top equation has the x coefficient be 8.
