Jack's pet dog has been prescribed 40 mg of a medicine per day. each pill of the medicine has 12 mg of the medicine. jack has to give his dog a total of 20 pills. if jack gave his dog medicine for x days, use the expression below to interpret the situation. : 12 20 − 40x part a. what does 240 represent? part b. what does the 40x represent? part c. what does the entire expression represent?

a. 240 represents the 12 mg multiplied by the 20 pills.

b. 40x represents the the mg of medicine per day, and how many days Jack has to give the medicine to his dog.

c. the entire expression represents how to find out how many days Jack gave his dog medicine.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
