Answer:
<em>Solution; - 4 / t + 1</em>
Step-by-step explanation:
See procedure below;
( 12 - 4t ) / ( t^2 - 2t - 3 ) ⇒ Factor out common term - 4 in 12 - 4t,
- 4 * ( t - 3 ) / ( t^2 - 2t - 3 ) ⇒ Break bottom expression into groups,
- 4 * ( t - 3 ) / ( t^2 + t ) + ( - 3t - 3 ) ⇒ Factor out t from t^2 + t,
- 4 * ( t - 3 ) / t * ( t + 1 ) + ( - 3t - 3 ) ⇒ Factor out - 3 from - 3t - 3,
- 4 * ( t - 3 ) / t * ( t + 1 ) + ( - 3 * ( t + 1 ) ) ⇒ Factor out common term t + 1,
- 4 * ( t - 3 ) / ( t + 1 ) * ( t - 3 ) ⇒ Cancel out like term t - 3,
<em>Solution; - 4 / t + 1</em>
Answer: 4
Step-by-step explanation:

Answer:
The student's weighted mean score is 92.2.
Step-by-step explanation:
To find the student's weighted mean scored, we multiply each grade by it's weight.
Grades and weights:
Homework: Grade of 86, weight of 20% = 0.2
Quiz: Grade of 87, weight of 5% = 0.05
Quiz: Grade of 91, weight of 5% = 0.05
Project: Grade of 98, weight of 45% = 0.45
Final Exam: Grade of 88, weight of 25% = 0.25.
What is the student's weighted mean score?
0.2*86 + 0.05*87 + 0.05*91 + 0.45*98 + 0.25*88 = 92.2
The student's weighted mean score is 92.2.
