5) k/35=3/7 : cross multiply
    35*3=7k   : simplify
    105=7k     : divide both sides of  the equation by 7
    k=15

6) 3/t=18/24  :cross multiply
     18t=24*3  :simplify
      18t=72   : divide both sides of the equation by 18
       t=4

7) 10/8.4 = 5/m  :cross multiply
    10m=5 * 8.4  :simplify
     10m=42   :divide both sides by 10
      m=4.2

5+k-5k=-4k+6 solve for k
marissa [1.9K]

Hey there

the answer is

5+k−5k=−4k+6

5+k+−5k=−4k+6

(k+−5k)+(5)=−4k+6

−4k+5=−4k+6

−4k+5+4k=−4k+6+4k

5=6

5−5=6−5

0=1

thank you

best regards

Find the domain of the rational expression: x-4/2x-6
marin [14]

Answer:

All real numbers except 3

Step-by-step explanation:

Given

\frac{x - 4}{2x - 6}

Required

Determine the domain

We start by writing the following inequality

2x - 6 \neq  0

Add 6 to both sides

2x -6 + 6 \neq = 0 + 6

2x \neq  6

Divide both sides by 2

\frac{2x}{2}\neq  \frac{6}{2}

x \neq  \frac{6}{2}

x \neq = 3

<em>As such, the domain of x is all real numbers except 3</em>
