Answer:
It takes one minute for both of them to eat one scoop.
Step-by-step explanation:
How long does it take them to eat 1 scoop of ice cream working together?
Jada: 2/5 = 0.4 per minute
Noah: 3/5 = 0.6 per minute
0.4+0.6 = 1 scoop per minute
How long does it take for Noah to eat his 3 scoops of ice cream in 5 minutes?
5 minutes???
Answer:
<u>x = 14</u>
Step-by-step explanation:
4x + (2x + 6) = 90
6x + 6 = 90
subtract both sides by 6:
6x + 6 <em>- 6 </em>=<em> </em>90 <em>- 6</em>
6x = 84
divide both sides by 6
6x/6 = 84/6
x = 14
double check:
4*14 + (2*14 + 6) = 90
56 + 28 + 6 = 90
Have a nice day!

The plot diagram is attached for better elaboration of the problem and its solution.
The limand is continuous at <em>x</em> = -1, so
![\displaystyle\lim_{x\to-1}\frac{x^{10}+x^3+1}{x-1}=\frac{(-1)^{10}+(-1)^3+1}{-1-1}=-\dfrac{1-1+1}2=-\dfrac12](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Clim_%7Bx%5Cto-1%7D%5Cfrac%7Bx%5E%7B10%7D%2Bx%5E3%2B1%7D%7Bx-1%7D%3D%5Cfrac%7B%28-1%29%5E%7B10%7D%2B%28-1%29%5E3%2B1%7D%7B-1-1%7D%3D-%5Cdfrac%7B1-1%2B1%7D2%3D-%5Cdfrac12)
