You have already run 4 miles. if you run at a speed of 8 miles per hour, how many total miles will you run in 2 more hours? choose the correct equation and solution to this problem.

a.8x-4=y b.4+8x=y c.4+8+x=y d.8x-y=4
8(2)-4=y 4+8(2)=y 4+8+(2)=y 8(2)-y=4
16-4=y 4+16=y 14=y 16-y=4
12=y 20=y y=12

Adriveway is 40 yards long about how many meters long is it

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?
