Each student worked on 115 math problems.
Step-by-step explanation:
Given,
Problems solved in 4 hours = 8970
Number of students in competition = 78
As each student solved same number of problems, we will divide the total problems solved by number of students to find the amount of problems solved by one student.
Problems solved by one student =
Problems solved by one student = 115
Each student worked on 115 math problems.

Each student works 115 problems.
Explanation:
I'm going to copy and paste the question here, and bold important info.
"Rayville Elementary sponsors a math competition for 78 students. During the competition, the students work a total of 8,970 math problems in 4 hours. Each student works the same number of problems. How many problems does each student work?"
Now everything not bolded? Forget about it. All you need to know is that there are 78 students. They all do 8,970 # of problems. And all the students do the same amount. Now you just have to divide the # of probs. by the amount of students in the competition, and you have your answer.
8970÷78=115
Hope that helped!
Answer:
(1/2)(8x³ + x² - 6x + 12)
Step-by-step explanation:
Next time, please share the possible answer choices. Thanks.
Multiplying all four terms of the given polynomial by 2 results in
x² - 6x + 8x³ + 12
Rearranging these terms in descending order by powers of x:
(1/2)(8x³ + x² - 6x + 12)
Note that we cannot just ignore that '2' in the denominator, because the given polynomial is an expression, not an equation.
