Answer:

12 + 8k² + k³ - 9k⁴

8 + k³ - 6k⁴ + 4 - 3k⁴ + 8k²

(8 + 4) + (8k²) + (k³) + (-6k⁴ -3k⁴)

(12) + (8k²) + (k³) + (-9k⁴)

In Kayllie'srecipe for lemonade, the ratio of lemons to water is 7 to 4. People are complaining that the lemonade is too weak. W
katrin [286]

Answer:

B.) 10 to 5 and D.) 8 to 4.

Step-by-step explanation:

Since we are trying to make the lemon taste stronger, there would need to be more lemons than water. The ratio would need to have a larger difference than 7:4. The difference is 3.

Choice A has a difference of 2. Two is less than 3 so this would taste more watery than lemony. Choice C has a difference of 3. Because we want a <em>stronger</em> lemon taste, this won't work. It would taste the same.

Choice B has a difference of 5. This is greater than 3 so the lemon taste will be stronger. Choice D has a difference of 4, this is also greater than 3 and will also make the taste of lemon stronger.

Hope this helps,

-1/3+4+2/3 what is the answer plz and thank you
koban [17]
Hi there!

-  \frac{1}{3}  + 4 +  \frac{2}{3}  =
First we rearrange the sum in order to add both of the fractions first. We can rearrange because the only thing we need to do is adding.

-  \frac{1}{3}  +  \frac{2}{3}  + 4 =
Add the fractions.
** If you don't get this, think of this story: you lack 1/3 of an apple pie and someone gives you 2/3 of pie. How much pie do you have left?
- 1 / 3 + 2 / 3 = 1 / 3 **

\frac{1}{3}  + 4 =
Finally add 4 to our found fraction.

\boxed{ 4\frac{1}{3} }
Therefore, the answer is 4 1/3.
