Answer: 5040ways
Step-by-step explanation:
This is a circular permutation question. Arrangement of objects in a circular path is (n-1)! where n is the amount of object. Since there are 8 students sitting in a circle excluding their teacher, they can sit in (8-1)! ways i.e 7! ways
7! = 7×6×5×4×3×2×1
7! = 5040ways
This means the students can sit in a circle in 5,040 ways

Answer:
Step-by-step explanation:
Given the equation 9x = 88, to get the value of x we will apply the division property of inequality. The division property of equality is the property applied to an expression by dividing both sides of an expression with the same constant without compromising the equality sign i.e after division, the expression at both sides of the expression still remains unchanged.
From the expression
9x = 88
Divide both sides by the coefficient of x i.e 9 (division property of equality)
9x/9=88/9
x = 9 7/9
<em>Hence the property that was used to solve the equation is the division property of equality</em>
