First, you must distribute 2(3x-1).
To do that, you will multiply 2•3x, and 2•-1 because you are taking the number outside of the parentheses and multiplying (distributing) it to all the numbers inside
After distributing, the left side of your inequality will be 6x-2
Now you have

To find the value of x, you must subtract an x value from both sides of the equation, as well as a constant from each side.
so you have

And that will make the equation

Now, divide the variable side, ***BUT, because you are dividing by a negative number in an inequality, the inequality will switch sides.
Then, the value of x is greater than or equal to 2
Answer: 4
Step-by-step explanation:
Hi, to answer this question, first, we have to subtract the amount of fabric used (3yd) to the total fabric that Demarco has (6yd)
6 -3 =3yd
Finally, we have to divide the result by the length of each strip piece (3/4yd)
3÷ 3/4= 4 pieces
There are 4 3/4 yd long strips.
Feel free to ask for more if needed or if you did not understand something.
Okay so combine like terms
10x-4x= 6x
2-8= -6
6x=-6
x= -1
Now to check:
10(-1)-2=4(-1)-8
-10-2=-4-8
-12=-12
