Answer:

\frac{5}{6} minutes

Step-by-step explanation:

Let's find unit rate of each.

<u>Jada</u>

2 scoop in 5 minutes

So,

1 scoop in 5/2 = 2.5 minutes

<u>Noah</u>

3 scoop in 5 minutes

So,

1 scoop in 5/3 = 1.25 minutes

These are the times. Time and rate are inverses of each other. So the rates of each is:

Jada = 1/2.5 = 0.4

Noah = 1/1.25 = 0.8

Working together, we add the rates and find the time:

(0.4+0.8)*t = 1

1.2t = 1

t = 1/1.2 = \frac{5}{6} minutes

So, they take \frac{5}{6} minutes to eat one scoop, working together

Solve x^2+11X&lt;-8 Urgent please help!!!!!
Tamiku [17]
Add 121/4 to each side:
x²+11x+121/4 < 121/4-8
x²+11x+121/4 < 89/4
(x+11/2)² < √89/2 ⇒ -√89/2 < x+11/2 < √89/2
-11/2-√89/2 < x < -11/2+√89/2
