Solve for k. 9/2k-3=4/k+1
Ivenika [448]
You'll need to use parentheses here to convey this problem accurately to possible helpers.  Unsure of whether you mean (9/2)k -3 or  9 / (2k-3).

I will assume that you mean:

    9           4
------- = ---------
2k-3        k+1

Cross mult:  9k+9=8k-12, so k= -21.

If that's not what you expected, then try again to present the problem without ambiguities.

NEEED HELP THANK YOU
Misha Larkins [42]

Answer:

<h2>z = -1</h2>

Step-by-step explanation:

Given the equation;

\frac{1}{z+1} +\frac{5}{z+5} = \frac{4}{z^2+6z+5}\\\

Find the LCM

\frac{1(z+5)+5(z+1)}{z^2+6x+5} = \frac{4}{z^2+6z+5}\\\\1(z+5)+5(z+1) = 4\\Expand\\z+5+5z+5 = 4\\6z+10 = 4\\6z = 4 -10\\6z = -6\\z = -6/6\\z = -1\\

Hence the value of z that satisfies the equation is -1

Angle W and angle X are congruent. If their sum is 121 degrees, what is the measure of angle X?
Taya2010 [7]
The measure of angle x is 60.5. Congruent means they’re the same so you would divide 121 by 2 and get 60.5.
