What is the equation. For a field trip 4 students rode in cars and the rest filled nine busses. How many students were in each bus if there were 472 students on the trip.

4x - 9 = 472
4x - 9 = 472

4x + 9 = 472
4x + 9 = 472

9x - 4 = 472
9x - 4 = 472

9x + 4 = 472

9x + 4 = 472

Step by Step Explanation

We know there are 9 buses, but we don't know how many students are on the buses, so that makes the first part of the equation 9x.

We also know there are 4 students in cars, so we now have an equation of 9x + 4.

We also know there is a total of 472 students altogether, so now our final equation is 9x + 4 = 472

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
