Question 550677: I have a few problems with a worksheet I am doing, that do not understand can you please help me?
--
#1# Find the LCD of the fractions in the equation 4.5x / 2x+5 = 2x / x^2
I keep getting the answer (2x+5)(x) But it does not seem correct to me.
----
#2# Solve each equation if no real answer then select no real answer.
x / x-5 = -2x/x
I keep getting x=10 in every way I try to solve the problem and it is not listed as one of the possible answers, I marked no real solution.
-----
#3# For this problem I do not understand on how to attempt it.
Find the focal length of the magnifying glass if you can see the butterfly clearly when your eye is 5.5 cm away from the glass and the glass is 25 cm away from the butterfly. The formula is 1/s + 1/t = 1/f.
I do not understand on how to do it.
----
#4# Simplify the rational equations.
x+5 / 3x+15
I think it is in the simplist form already but I know you can divide the 5 into the 15 but can't divide the 3x into 3 .
x+5/4 divided by (x^2+5x)
I got 1/4x but i do not think it is correct.
---
#5#
Solve the rational equation
x^3 / 16 = x^6 / 2
I keep getting an answer that is not listed as a possible answer.
----
I am using the symbol "/" as the fraction symbol not the division symbol.
And thank you for your help.
