Answer:
10 units
Step-by-step explanation:
In this equation the parenthesis act as a multiplier, so you take w(2w + 2) = 40.
the variable w represents the number 1, so you multiply the numbers within the parenthesis.
w x 2w = 2w
w x 2 = 2w
so now you have 2w + 2w = 40
add the w's for 4w = 40
Now you need to get rid of the number next to the W.
divide the four from the W and divide the 40 as well
4w/4= w
40/4 = 10
W=10
So all you do is you divide 2 1/2 by .25 and you get 10 then you know one fourth or 25% of that package is 10 berries so the rest or 30% left over is 30 berries.

This is because a number die is random and if it were based on even and odd, the chances would be 50/50
C; You know this because it asks for a dependent event. This means that a first event must occur that automatically changes the results for the following events. When you see dependent, look for without replacement.
To turn a whole number into a fraction, you put that number over 1. So 5 becomes 5/1, because 5 divided by 1 equals 5... and a fraction basically means the numerator (top number) divided by the denominator (bottom number).
