Ok,so you can represent the students as K and Y as the cookies eaten.X is your  constant of proportionality (the number you multiply to k to get y).

For the first one,14/2 which equals 7.Try the next set,21/3=7 also and finally 35/5=7.You can see that the C.O.P is 7.

What is 3x3-45 divided by (4+1)
Lorico [155]

Answer:

3x3-45÷(4+1) is 0.

Step-by-step explanation:

We have to do order of operations so we follow PEMDAS:

P is for Parentheses so we do what's in parentheses first:

(4+1)=5

E is for Exponents but we don't have exponents.

Next is M and D for Multiplication and Division. We have division before multiplication so we should do division first:

45÷5=9

We now have multiplication:

3x3=9

Now we have A and S for addition and subtraction

We don't have addition so we'll do subtraction:

9-9=0

The final answer is 0.

Hope this helps! :)

a printer charges a fixed setup cost plus $0.40 for every 40 copies. if 320 copies cost $43.20 how much will it cost to print 12
Dovator [93]
So if we take this equation down a set by making 1200 into 120 and 40 into 4 so if we divide 120 by 4 then we get 30 so we times 30 by .4 and get 12 we then add the zero on the end and get $120
