Cormac is making 27 phone calls each week as part of a fundraiser. Last week, he made 13 phone calls on weekdays. Which equation could be used to find x, the number of phone calls he made last week on weekend days? A. x - 27 = 13
B. 13 + x = 27
C. x + 27 = 13
D. 27x = 13

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

Im literally having a mental breakdown
