A recipe that makes 8 jumbo blueberry muffins calls for 1 1/2 teaspoons of baking powder how much making baking powder is needed
nirvana33 [79]

we know that

For make 8 jumbo blueberry muffins is needed 1\frac{1}{2} teaspoons of baking powder

1\frac{1}{2}=1.5

So

by proportion

\frac{8}{1.5} =\frac{36}{x} \\ \\ 8x=36*1.5\\ \\ x=\frac{36*1.5}{8} \\ \\ x=6.75

x=6\frac{3}{4} teaspoons of baking powder

therefore

the answer is

6\frac{3}{4} teaspoons of baking powder

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}

3x + 2y = 1 5x – 2y = 39
Alekssandra [29.7K]
3x + 2y = 39
-3x -3x

2y = 39-3x
— ———
2 2

y= 19.5 - 3x/2
plug (19.5 - 3x/2) for y

1.5x - 2(19.5 - 3x/2)= 39
x= 17.33333333334

What is the answer to tue eqation <br> 3x+5y+10-2x
Llana [10]
First of all, this is an expression, since it is not set equal to anything; therefore, you can't solve it.
However, you can simplify it.
The simplified expression would be

x+5y+10

Hope this helps!
