Step-by-step explanation:

Note: The data in this question are merged. They are therefore sorted before answering the question as follows:

A student's math 123 grades are shown below.

Category          Weight        Grade

Homework          15%             36

Quiz                     15%             60

Project                20%             75

Exam 1                 15%              71

Exam 2                15%               9

Exam 3               20%             92

Calculate the student's final grade in math 123. Write your answer as a percent rounded to the nearest tenth. Don't include the percent sign.

Explanation to the answer is now given as follows:

The final grade of the student in math 123 can be calculated by adding together the products Weight and Grade obtained of each category as follows:

Final grade = (15% * 36) + (15% * 60) + (20% * 75) + (15% * 71) + (15% * 9) + (20% * 92) = 59.8%

The answer is already rounded to nearest tenth as required by the question.

Since the question also states that the percent sign should not be include, the student's final grade in math 123 is therefore 59.8.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
