Answer:

x = 6

Step-by-step explanation:

Hello!

x + 22 is equal to the sum of 5x - 6 and 4.

<h3>Solve for x</h3>
  • 5x - 6 + 4 = x + 22
  • 5x - 2 = x + 22
  • 4x - 2 = 22
  • 4x = 24
  • x = 6

The value of x is 6.

Solve the equation 12(-11x + 5) + 7 = 2 (x-9) - 451 algebraically. Answer as a reduced fraction only.
Pachacha [2.7K]

The value of x in the equation is 4.2.

<h3>How to calculate the value?</h3>

It should be noted that the equation given is:

12(-11x + 5) + 7 = 2 (x-9) - 451

This will be computed thus:

12(-11x + 5) + 7 = 2 (x-9) - 451

-132x + 60 + 7 = 2x - 28 - 451

Collect like terms

-132x - 2x = - 28 - 451 - 60 - 7

-130x = -546

Divide

x = 546/130

x = 4.2

The value of x in the equation is 4.2.

One canned juice drink is 15​% orange​ juice; another is 10​% orange juice. How many liters of each should be mixed together in
Vaselesa [24]

Answer:

3 liters of 15% and 2 liters of 10%

Step-by-step explanation:

You can set up a table that says the number of liters multiplied by the percent juice equals total percent of juice in L liters:

              L      *      % juice    =         %L

That is the main set up for the table.  We will put in values for the percent juice right away, because they were given to us.  Remember that percentages need to be expressed as decimals in order to use them in equations.

              L     *       % juice       =        %L

15%                          .15

10%                          .10

___________________________________

13%                           .13

Easy enough so far.  We know that the 15% juice canned juice contains 15% juice.  No secrets there at all.  We also made a row for the mixture that needs to be 13% juice.  Next we know that the total amount of the mixture has to be 5 liters.  If we mix one juice with another and the total has to be 5 liters, then we have an unknown amount of one juice, and 5 - that unknown amount of the other juice.  Filling in we have:

             L      *      % juice       =       %L

15%        x                   .15

10%      5 - x                .10

______________________________

13%         5                   .13

Our equation tells us that we have to multiply the L times the % to fill in that last column:

             L      *      % juice      =       %L

15%        x     *          .15           =      .15x

10%      5-x    *          .10          =     .10(5 - x)

__________________________________

13%         5      *        .13           =     .65

We are told from the problem we are adding the 2 juices to get the mixture, so we will add the rows in the last column and set it equal to .65:

.15x + .10(5 - x) = .65

Let's multiply everything by 100 to get rid of all those decimals:

15x + 10(5 - x) = 65

Distributing and combining like terms:

15x + 50 - 10x = 65 and

5x = 15

x = 3

That means that we need 3 liters of the canned juice that is 15% juice.

5 - 3 = 2...and 2 liters of the canned juice that is 10% juice to get the correct number of liters of 13% juice.

Please help guys this khan and litteraly have this unit test please guys illl mark brainliest
tankabanditka [31]

Answer:

x=36

Step-by-step explanation:

So, lets go over what we know:

16 is equal to 4/9ths of x.

As a equation, this looks like:

16 = \frac{4}{9}x

We can begin to solve for x by multiplying both sides by the denominator, 9, which gets us:

16*9 = 4x

=

144 = 4x

Then we can divide by the coefficent of x, which is 4, to get our answer:

\frac{144}{4} = x

=

36=x

This is our answer! Hope this helps! :3
