Answer:

A) X + Y = 12

B) 10Y + x = 10x + Y -18

B) 9Y = 9x -18 multiplying A) by -9

A) -9Y = 9x - 72  adding A and B we get

0 = 18x -90

x = 5

The number is 75

Double-Check

7 + 5 = 12

75 -57 = 18

​Dolbear's law states the relationship between the rate at which Snowy Tree Crickets chirp and the air temperature of their envi
tia_tia [17]
I assume that if we write the equation in its mathematical form it will appear like this:
                                  T = 50 + (N - 40)/4
Substituting the value of T given,
                                  58 = 50 + (N-40)/4
The value of N from the generated equation above is equal to 72. Therefore, the Snowy Tree Crickets chirp 72 times per minute at a temperature of 58°F.

Which phrase is the best description of the association between variables X and Y?
Elodia [21]
The variables have a negative association/correlation, because when one value increases (ex: x) the other decreases (see y)
If you would put a line through the dataset most of the points would be quite a bit off the line so the association is only moderate and not strong

so the answer is it is a "moderate negative association"
