Solve the equation.<br> 6x−12=3(2x+5)
nordsb [41]

Let's solve your equation step-by-step.

6x−12=3(2x+5)

Step 1: Simplify both sides of the equation.

6x−12=3(2x+5)

6x+−12=(3)(2x)+(3)(5)(Distribute)

6x+−12=6x+15

6x−12=6x+15

Step 2: Subtract 6x from both sides.

6x−12−6x=6x+15−6x

−12=15

Step 3: Add 12 to both sides.

−12+12=15+12

0=27

Answer:

There are no solutions.

jasenka [17]

Answer:

x-0.33x  = 0.67x

Step-by-step explanation:

Given :  A new soup recipe contains 33% less sodium per serving than the old soup recipe.

The old soup recipe contained x milligrams of sodium per serving.

To Find: Which of the following expressions could represent the amount of sodium per serving, in milligrams, in the new soup recipe

Solution :

Since we are given that old recipe contains x milligrams of sodium per serving

And new recipe  contains 33% less sodium per serving than the old soup recipe.

So, 33%of x = 0.33x

Since new recipe contains 33% less sodium than old recipe:

⇒x-0.33x

or

⇒(1-0.33)x

⇒0.67x

Thus expressions which could represent the amount of sodium per serving, in milligrams, in the new soup recipe :

x-0.33x or 0.67x
