record what each expression represents according to the facts.
car #1 travels m miles on one gallon of gas, and uses x gallons of gas each day.
car #2 travels l miles on one gallon of gas, and uses y gallons of gas each day.
1) mx =

2) x + y =

3) m – l =

1) what is the measure of the exterior angle, ∠uvw ? 2) in triangle man, what is the measure of the exterior angle at n (in degrees)?

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?

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
