An Easter basket contains eggs of three different colors. Find the total number of eggs in the basket if 2 7 of all eggs are gre
mrs_skeptik [129]

Answer:

Total number of eggs in basket = 56

Step-by-step explanation:

Let z be the total number of eggs

Green eggs = \frac{2}{7} × z   ........1

Blue eggs =  \frac{1}{4} × z    .......2

Rest of eggs = 26  ........3

The addition of 1, 2 and 3 is equal to z  

\frac{2}{7} × z + \frac{1}{4} + 26 = z

\frac{8z + 7 z}{28} + 26 = z                        ∵GCF for 4 and 7 is 28  

\frac{15z}{28}  + 26 = z

15z + (26 × 28) = 28z                ∵ multiply both sides by 28

15z + 728 = 28z

28z - 15z = 728     .......... rearranging above equation

13z = 728  ⇒   z = \frac{728}{13}   ⇒  z = 56

Total number of eggs = z = 56

How much is 2 plus 9​
Rama09 [41]

For this case we must represent the following expression algebraically, in addition to indicating its result:

"2 plus 9"

So, we have:

2 + 9 =

By law of the signs of the sum, we have that equal signs are added and the same sign is placed:

2 + 9 = 11

Divide -3x3 - 4x2 + 4x +3 by x-2
kobusy [5.1K]

Answer:

-3x² - 10x - 16 r. \dfrac{-29}{x-2}

Step-by-step explanation:

You can easily do this through synthetic division:

First step is to get all the numeric coefficients of the expression and write them down. Don't forget to bring their signs along with them.

-3x³ - 4x² + 4x +3

    | -3     -4     +4    +3

    |______________

Next we find the root that is associated with the divisor:

x  - 2 = 0

x = 2

We use this and put it outside:

 2   | -3     -4     +4    +3

      |______________

Okay now we bring down the first coefficient:

  2  | -3     -4     +4    +3

      |______________

        -3

Then we multiply it by the root and put the product under the next coefficient:

2  x - 3 = -6

2  | -3     -4     +4    +3

    |<u>         -6                  </u>

      -3

Then we add them:

2  | -3     -4     +4    +3

    |<u>         -6                  </u>

      -3    -10

Do the same steps until the end:

2  | -3     -4     +4       +3

    |<u>         -6      -20     -32              </u>

      -3     -10     -16     -29

Now that you have that, remember that since the divisor is in the 1st degree, quotient will have a degree will be one degree below as well.

-3x² - 10x - 26

Your last coefficient is going to be your remainder:

-3x² - 10x - 16 r. \dfrac{-29}{x-2}
