Question

You score an 84 on the first of two exams. Write and solve an equation to find the score x that you need on the second exam to have a mean score of 88.

Answer 1

(84+x)/2=88 You need at least a ninety two.

Step-by-step explanation: First realize that average means the sum of all numbers divided by how many numbers there were. For that reason, I wrote the sum of the exams divided by two which equals eighty eight. Isolate the variable. Multiply two to the other side and subtract eighty four to get final answer.
