I don’t know how to make a rule:(
Yuri [45]

Answer:

*assuming you know the concept of proportionality*

since L is directly proportional to T, an increase in L will result in an increase in T

so the solution of the first part is increases

in part 2, y is inversely proportional to x

which means that an increase in y will result in a decrease in x and vice-versa

So the answer of the second part is decreases

in part 3, since x is directly proportional to y, an increase in x will result in an increase in y

Jack's mother gave him 50 chocolates to give to his friends at his birthday party. He gave 3 chocolates to each of his friends a
Natasha_Volkova [10]

Answer:

16 friends

Step-by-step explanation:

Right at the beginning, you can take the 2 chocolates Jack was left with out of the 50 chocolates Jack had at the beginning. That equals 48 chocolate bars, so we know that Jack gave his friends a total if 48 chocolates

50 - 2 = 48

Now that you have the number 48, you are really close to the answer.

If you know that he gave each if his friends 3 chocolates, you can make that into an equation and put it into a calculator. That would look like this:

48 \div 3 = 16

The reason you do 48 ÷ 3 is because Jack divided his 48 chocolates into groups of 3 to give to each of the other kids.

You get the answer 16, which means the answer is 16 kids at his friend's birthday party.
