Answer:
110 = points possible
Step-by-step explanation:
The points received equals the points possible times the percent
99 = points possible * 90%
Changing this to decimal form
99 = points possible * .90
Divide each side by .90
99/.90 = points possible *.90/.90
110 = points possible
The solutions are -6 and 6
That row of Pascal's triangle is 1 3 3 1 for the coefficients so
(x+6)³ = 1x³ + 3x² + 3x + 1
Let the number = X
You have X^8 / X^5
When dividing two numbers with powers, Simplify the expression by subtracting the powers.
8-5=3
so X^8 / X^5 becomes x^3
Now you have x^3 = 64
To find x take the cubic root of 64:
X = ∛64
X = 4
The number is 4
