Answer:
Sorry i also have no idea
Step-by-step explanation:
We are given that we have $25 to pay for 6 fishing lures.
We can make an equality for this as follows:
Suppose price of one fishing lure is x dollars.
So we will use unitary method to find price of 6 fishing lures.
Price of 6 fishing lures = 6 * ( price of one fishing lure) = 6* x = 6x
Now we only have 25 dollars with us, so the price of 6 fishing lures has to be less than or equal to 25 dollars.
So creating an inequality,

Now in order to find price for one fishing lure, we have to solve this for x.
Dividing both sides by 6 we have,

Converting to decimal,

Answer : The price of one fishing lure must be less than or equal to $4.167

if you have already covered slopes, you could also get it that way, in fact is simpler that way.
4 I think because you subtract all since it's 60 min
Yes they are equivalent expressions. If you take the z to the power of two, and subtract that from the other z to the power of two, it is zero. So you are left with four which is the answer
