1, 3, 5, 7, 9 are the possible digits for the tens digit. Notice they are all odd.
My reasoning:

When you multiply any 2 numbers together, the last digit of the result will be the last digit of the product of the original last digits (ex. 12*7 = 84: 7*2 = 14 : 4 is last digit)
</span>
The last TWO digits of the result will be the same as the last 2 digits of the product of just the last two digits. (ex, 1422*234 = 332,748: 22*48 = 748 : 48 are last two digits )
If is a perfect square ends in 6, the last digit squared must end in 6 as well.
The only single digit numbers squared that end in 6 are: 4*4=16 and 6*6=36
They are the only 2 so the number that is being squared must end in 4 or 6
Let the second last digit be X. X can be any digit.
So the last 2 digits of our number that is being squared are either X6 or X4
That is, the last 2 digits of the number are either (10X+6) or (10X+4),
this will result in X always being an odd number.
The line contains (9,y) and (-6,3) Then y is 13
<em><u>Solution:</u></em>
Given that a line contains (9, y) and (-6, 3)
Slope of line is 
To find: y
<em><u>The slope of line is given as:</u></em>
<em><u>Substituting the values in formula,</u></em>
Substitute 
2(-6 - 9) = 3(3 - y)
Multiplying the terms with terms inside bracket
-12 - 18 = 9 - 3y
Move the variable to one side
-30 = 9 - 3y
On solving we get,
3y = 30 + 9
3y = 39
Divide both sides by 3, we get
y = 13
Thus y = 13
It depends on how big you want the cookies to be.1 1/2 cups of sugar thought
velocity of the boat = 36miles/3 hours
divide denominator and numerator by 6 respectively
6 miles/0.5hrs
thus, the we can say that the boat will travel 6 miles in 0.5 hour
