Use the fact that 1 hour = 60 minutes, from which you can create your conversion factor: 1 = hour / 60 minutes. That permit you to multiply the number of miles per hour times [1 hour/60minutes] to convert 50 miles per hours to miles per minute. This is the calculation: 50 miles/hour * [1hour/60minures] = 0.833 miles / minute
Rewrite it as 5x^2 -20x-3x+12
then (5x^2 -20x)(-3x+12)
then use gcf and u will get the answer in a binomial form
I can help you because I know how to convert fractions to mixed numbers, but what is the question exactly?
Answer:
I believe the answer is A
He is correct. If the second equation is multiplied by 2 and added to the first equation, the result is 0=3 , which means the system has no solution.
