Three hundred students went on a field trip to the zoo. Six buses were filled and 12 students rode in cars. How many students were on each bus?
There were a total of 300 - 12 = <<300-12=288>>288 students who rode the buses.
There were 288 / 6 = <<288/6=48>>48 students on each bus. Answer: \boxed{48}.
To find out how many students were on each bus, we first need to subtract the students who rode in cars from the total number of students, and then divide the result by the number of buses used.
Step 1: Find the total number of students who rode in cars.
12 students rode in cars.
Step 2: Find the total number of students who went on the buses.
300 students in total - 12 students who rode in cars = 288 students on the buses.
Step 3: Find the number of students on each bus.
Since there were 6 buses, we divide the total number of students on the buses by the number of buses used.
288 students on the buses / 6 buses = 48 students on each bus.
Therefore, there were 48 students on each bus.
To find out how many students were on each bus, we need to divide the total number of students by the number of buses.
Step 1: Calculate the number of students who rode in cars.
Given that 12 students rode in cars, we subtract this number from the total number of students.
300 - 12 = 288
Step 2: Calculate the number of students on each bus.
Since six buses were filled, we divide the remaining students by the number of buses.
288 รท 6 = 48
Therefore, there were 48 students on each bus.
Clara wants to bike 112 miles this week. That is 20 miles less than 2 times the number of miles she biked last week. How many miles did she bike last week?
Let's assume the number of miles Clara biked last week to be x.
According to the given information, Clara wants to bike 20 miles less than 2 times the number of miles she biked last week.
So, the equation representing this information is: 2x - 20 = 112.
To find x, we need to solve this equation.
Adding 20 to both sides, we have: 2x = 112 + 20.
Simplifying the right side of the equation, we get: 2x = 132.
Dividing both sides of the equation by 2, we have: x = 132 / 2.
Thus, Clara biked x = 66 miles last week. Answer: \boxed{66}.
