First, you’re gonna find your rate of change for minutes per mile by dividing the minutes by the miles (25/3.5), which equals about 7.14 minutes (but if you don’t round, it’s 7.14285714 minutes) and then you’ll multiply this by 7 miles (7.14285714*7) and get 50 minutes for 7 miles.
Restaurant and super market have the fastest inventory.
160 Students. If you set it up as a proportion, you will have 12/30 is equal to x/400. If you cross multiply you get 4800=30X. Then divide 4800 by 30 and you get X=160.
So, we need to convert the fractions into equivent ones.
So, in order to get the numerator of the first fraction to match the numerator of the second fraction, we must mutltiply it by 2/2
Your first answer is 6.
Then, in order to get the denominator of second fraction to match the other side, you must multiply by 3/3
Your second answer is 3
