What is the solution of the equation 6 – 2x = 1? round your answer to the nearest ten-thousandth.

x = 2.5

Step-by-step explanation:

We need to find out the x.

First, we put together on one side of the equation the terms with an x and on the other side the terms without it. For that, we subtract 6 on both sides of the equation:

6 - 2x - 6 = 1 - 6

-2x = -5

Now we divide both sides by (-2):

-2x/-2 = -5/-2

x = 5/2 = 2.5

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
