One way to do this problem is to take 26.65 and divide it by all of the values from $2.01 to $2.99. If one of these goes in evenly with no remainder then that is the cost of each notepad. The quotient (answer when you divide) is the number of pads. Since we can’t have half a pad, the number must go in evenly (leave no remainder).
While we can check each of these, I noticed that 26.65 ends in a 5 and so is divisible by 5 so I decided to check 2.05 as a possible price and it went in evenly. The quotient is 13.
thus, there were 13 notepads and the cost of each is $2.05

Answer:
+120/169 or -120/169
Step-by-step explanation:
- let
where, alpha is some angle that satisfies the assumed condition.
- so,
[ taking cos to the other side or applying cos on both sides]
- now, substitute this in the given expression
as sin =
[by general trigonometry formula: ]
so if , we can get sin from the above formula as + or - 12/13
(because, after taking square root on both sides we keep + or -]
- as, sin
[by general trigonometry formula]
- here, now
so, the final value can be 120/169 or -120/169.
Answer:
24
Step-by-step explanation:
It is done by Middle term splitting.
Taking the general equation ax² + bx + c, by middle term splitting, "b" should be splitted such that the numbers either on adding or on subtracting must be equal to "b" and their products must be equal to "a x c".
For example, in the question it's already given that the equation 8x² + bx + c is middle term splitted into 8x² + px + qx + 3.
So, that means "p x q" must be equal to "8 x 3", i.e., 24.
