Simplify the following:
(y^6 y^8)/((2 x^2)/(x^4))
Combine powers. (y^6 y^8)/((x^2×2)/x^4) = (y^(8 + 6) x^(4 - 2))/2:
(y^(8 + 6) x^(4 - 2))/2
8 + 6 = 14:
(y^14 x^(4 - 2))/2
4 - 2 = 2:
Answer: (y^14 x^2)/2

Four less than nine times a number is one hundred twenty-two. Find the original number.

Tasya [4]

Answer:

The number is $14$

Step-by-step explanation:

Denote the original number by z. The expression "Four less than nine times a number is one hundred twenty-two" can be rewritten in an equation.

Our number is z, then the left hand side of the equation is 9z-4.

The right side of the equation is 122. Then the complete equation is $9z-4=122$ . Add 4 in both sides to get $9z=122+4=126$ . Now, divide by 9 in both sides to get $z=\frac{126}{9}=14$
