Answer:

<em>9 students</em>

Step-by-step explanation:

Assuming that these dots represent students, let us begin with the amount of students that answered 8 questions right;

Students who got 8 answers right ⇒ 4 students,

Students who got 8 answers right ⇒ 3 students,

Students who got 10 answers right ⇒ 2 students

Now we are to compute the value of the students who received 8 or more answers right, provided the questions are out of 10;

Students who received 8 or more answers right; 4 + 3 + 2 = 9 students

<em>Solution; 9 students</em>

Solve for x. 3/x-1 - 1/x^-1=5/x-1<br><br> Please show all work
navik [9.2K]

3/(x-1) - 1/(x^2-1) = 5/(x-1)

Subtract 3/(x-1) from both sides

-1/(x^2-1) = 2/(x-1)

Factor x^2 - 1

-1/[(x-1)(x+1] = 2/(x-1)

Multiply by (x-1)(x+1) on both sides

-1 = 2 (x+1)

-1 = 2x + 2

Subtract 2 from both sides

-3 = 2x

Divide by 2 on both sides

-3/2 = x
