3. An ice cream shop sells ice cream cones with exactly I of 3 ice cream favors in the cone. The 3 flavors are
vanilla, chocolate, and strawberry. Last Saturday, the
shop sold 42 cones, It sold 11 more with chocolate
than with vanilla and 2 more with vanilla than with
strawberry. How many comes with strawberry ice
cream did the shop sell that Saturday?

This can be solved using the strategy used in this post:

It comes down to calculating

(5+3−13)=(73)=7⋅6⋅51⋅2⋅3=35

What we are doing is the following: We create 5 'buckets' of flavors:

−−−|−−−|−−−|−−−|−−−

Now, we want do divide the three scoops over the 5 buckets. Below, a scoop is shown as O. Some possibilities are:

O|O|||O||OOO||etc...

There are 4 borders between the buckets and 3 scoops. Thus, there are (4+33)=35 possibilities

Step-by-step explanation:

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
