Two numbers total 10, and there difference is 12. Find a smaller of the two numbers.
Olenka [21]

Answer:

There doesn't seem to be numbers to answer that, do you have the question right? If it was a difference of 18, for example, the numbers would be 64 and 36.

Step-by-step explanation:

Find 2 numbers that added together, equal 10.

91

82

73

64

55

46

37

28

19

Then subtract them by their opposites. Find the numbers with the difference of 12.

91 - 19 = 72

82 -  28 = 54

73 - 37 = 36

64 - 46 = 18

55 - 55 = 0

46 - 64 = -18

37 - 73 = -36

28 - 82 = -54

19 - 91 = -72

There is no numbers with the difference of 12.

If it was a difference of 18, for example, the numbers would be 64 and 36.

Answer:

Since the question doesn't mention in what tide the answer should be, I will be giving a solution to both, the high and low tide. Hope this helps :)

Step-by-step explanation:

Using a cosine function, where time is measured in hours past high

tide:  y=4cos30x + 10

Using a cosine function, where time is measured in hours past low

tide:  y = 4cos[30(x-6)]+10
