Since we know it is between 80 and 99, the tens place can only either be 8 or 9.
If it is 8, the ones place is 5 since the digits must add to 13.
If it is 9, the ones place is 4 since, once again, the digits must add to 13.
Our options are 85 or 94. Based on the last clue, it is 85 since 8-5=3.
Final answer: 85
The midpoint of these two points is (-1, 8).
In order to find the midpoint, you must take the average of each part of the coordinates. You do this by adding them together and dividing by 2. We'll start with the x-coordinates.
(-1 + -1)/2 = -1
Now we'll use the y-coordinates.
(10 + 6)/2 = 8
This gives us the ordered pair of (-1, 8)
Answer:
Option b is correct.
Step-by-step explanation:
From the given condition : Seven less than the quotient of a number, x, and twelve is five times the number.
Here, the number is x
The quotient of a number x and twelve is expressed as , 
Seven less than the quotient of a number, x, and twelve is expressed as, 
Five times the number mean, 
Therefore, we have an equation in the form of <em>x</em> from the given condition as:
.
Answer:
x = 10 y = 2

Say he has 2 dimes (D), 2 nickels (N), and 2 quarters (Q). There are 3 * 3 = 9 choices for what he can pull out. How many will give at least 30 cents?
Q and N, N and Q, Q and D, D and Q
That's 4 out of 9. So, the probability is 4/9.
