Answer:
Method 1:
Find the Least Common Denominator (LCD) of all the denominators in the complex fractions.
Multiply this LCD to the numerator and denominator of the complex fraction.
Simplify, if necessary.
Method 2:
Create a single fraction in the numerator and denominator.
Apply the division rule of fractions by multiplying the numerator by the reciprocal or inverse of the denominator.
Simplify, if necessary.
To solve this, just take $80 and subtract her amount of money she has now, which is 8. $80-$8=$72
She needs $72

Answer:
x = 1 + i sqrt(7/2) or x = 1 - i sqrt(7/2)
Step-by-step explanation:
Solve for x:
2 x^2 - 4 x + 9 = 0
Divide both sides by 2:
x^2 - 2 x + 9/2 = 0
Subtract 9/2 from both sides:
x^2 - 2 x = -9/2
Add 1 to both sides:
x^2 - 2 x + 1 = -7/2
Write the left hand side as a square:
(x - 1)^2 = -7/2
Take the square root of both sides:
x - 1 = i sqrt(7/2) or x - 1 = -i sqrt(7/2)
Add 1 to both sides:
x = 1 + i sqrt(7/2) or x - 1 = -i sqrt(7/2)
Add 1 to both sides:
Answer: x = 1 + i sqrt(7/2) or x = 1 - i sqrt(7/2)
