Answer:
1.) x = 110

So for 3 to become 15 it would have to be multiplied by 5 because 3 x 5 = 15. And if I multiply the numerator by anything I always have to do the same to the denominator. So I multiply 22 x 5 = x. x = 110

2.) x = 72

For 16 to become 2 it has to be divided by 8 because 16 ÷ 8 = 2. And I have to do the same to the numerator of course, so i have to find x ÷ 8 = 9. I know the answer by memory, but for some it's easier to rewrite this as 9 × 8 = x. x=72

3.) c = 24

For 5 to become 40 it must be multiplied by 8 because 5 × 8 = 40. I have to multiply 8 by the numerator as well and 3 × 8 = 24. c = 24

The result is TR (20).
To determine the result of TR (915) - TR (895), the following logical-mathematical reasoning must be made:
We find a constant that is repeated in both values, which is TR.
In turn, both values have a different quantity, which multiplies that constant.
Therefore, you must perform this multiplication and then subtract the results, to obtain the final result.
- TR (915) - TR (895) = X
- 915TR - 895TR = X
- 20TR = X
Therefore, the result is TR (20).

we have to find address of element -5 in the matrix
We know that
horizontal line represents number of rows
vertical line represents number of columns
We can see that
-5 is in third row
and -5 is in second column
Suppose, we have element in matrix

Here , m is number of rows
and n is number of columns
so, we got


now, we can plug these values
and we get

In 52-card deck there are 36 numbered card and 52/4=13 spade card
so probability that you are dealt a numbered card is 36/52 =9/13 a spade card is 13/52=1/4
