Well, number 1 is A, or p = 6t. This is because the number of points is equal to the number of touchdowns times six. *6 = (6)(1) *12 = (6)(2) *18 = (6)(3), etc
Answer:
9(4y - 7) = 36y
^^multiple the bracket by the number outside the bracket
Answer:
11
Step-by-step explanation:
The average price of the 20 shirts is 600/20 = $30 each. So, we know that we can sell 20 shirts for $30 each to reach the goal.
For each $25 shirt we sell, we must also sell a $35 shirt to make the average price of the sale be $30 per shirt. That is any or all of the 10 pairs of $30 shirts can be replaced by a ($25, $35) pair. So, there are 10 additional ways to reach the goal.
The total number of possible combinations of shirt sales is 1 +10 = 11.
Answer:
I think that what you are trying to show is: If 
is irrational and 
is rational, then 
is rational. If so, a proof can be as follows:
Step-by-step explanation:
Suppose that is a rational number. Then and can be written as follows
Hence we have that
Then
This is a contradiction because we assumed that is an irrational number.
Then must be an irrational number.
