we know that
For make
jumbo blueberry muffins is needed
teaspoons of baking powder

So
by proportion

teaspoons of baking powder
therefore
the answer is
teaspoons of baking powder
Answer:
10
Step-by-step explanation:
523=4/3 pi r^3
124.86=r^3
5=r
d=2r
d=10
Answer:
-3x² - 10x - 16 r. 
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. 
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
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!
