Answer:
3
Step-by-step explanation:
Step 1: Isolate <em>y</em>
5y < 20
y < 4
When we figure out the inequality, we see that <em>y </em>has to be less than 4. Therefore, the highest integer value will have to be 3.
Answer: a) 
b) Cost of a macadamia nut chip cookie is $33.93 and the cost of triple chocolate cookie. is $3.77
c) Elimination method because it enables us to eliminate one of the variables.
Step-by-step explanation:
Let x be the cost of macadamia nut chip cookie and y be the cost of triple chocolate cookie.
Then according to the question we have the following equations:-

Multiplying 5 on both sides of the equation (2), we get
...............(3)
By using elimination method, subtract equation (1) from (3) we get

Substitute the value of y in (2), we get

It doesn't matter if there is 0, you still flip the inequality symbol.

Answer:
9/25 i think
Step-by-step explanation:
i got 9 from the tally marks, there was 9 tally marks,
and 25 is how much a quarter is
The expected value per game is -0.26. Over 1000 games, you can expect to lose $263.16.
To find the expected value, we multiply the probability of winning by the amount of winnings, the probability of losing by the amount of loss, and adding those together.
We have a 1/38 chance of winning; 1/38(175) = $4.61. We also have a 37/38 chance of losing; 37/38(5) = $4.87.
$4.61-$4.87 = -$0.26 (rounded)
To five decimal places, our answer is -0.26136; multiplied by 1000 games, this is $261.36 lost.
