What value of x is in the solution set of 3(x-4)greater than or equal to 5x+2
Gnesinka [82]

3(x-4)>= 5x+2

Distributing 3 on x-4

3(x)-3(4)>=5x+2

3x-12>=5x+2

Now we need to move x terms together and the numbers together and for that we subtract 5x to both sides and add 12 to both sides

-2x >=14

Now we need to get rid of -2, and for that we divide both sides by -2 and on dividing by negative number, the sign of inequality change , that is

x<=-7

What is 26/48 simplest form
Phoenix [80]

Answer:

13/14

Step-by-step explanation:

The GCF between 26 and 48 is 2. So divide 26/2=12 and 48/2=13  13/14. And after that you can not simplify anymore so 13/14 is 26/48 in it's simplest form.


Hope it helps!

3(x-7)+8=-20<br><br><br><br>can someone explain how to do this step by step​
Mrrafil [7]

3(x-7)+8=-20

Multiply the bracket by 3

(3)(x)(3(-7)+8= -20

3x-21+8= -20

3x-13= -20

Move -13 to the other side. Sign changes from -13 to +13.

3x-13+13= -20+13

3x= -7

Divide by 3

3x/3= -7/3

x= -7/3 or in mixed number : -2 1/3

Answer : x= -7/3 or in mixed number : -2 1/3
