Last week, you spoke with 800 customers in 40 hours."
marishachu [46]

Answer:

10 customers

Step-by-step explanation:

Hi!

Each hour has 60 minutes, so two half hour (30 minute) blocks. Thus, 1 hour = 2 half hours, so 40 hours = 80 half hours.

800 customers in 80 half hours, divide that:

800 customers / 80 half hours = 10 customers / half hour

So, your answer is 10 customers every half hour, or 10 customers every 30 minutes.

Ugo [173]

Answer:

x = -2

Step-by-step explanation:

Given :

\frac{8}{x+1} = \frac{-16}{x+4}

⇒ 8x + 32 = -16x - 16

⇒ 24x = -48

⇒ x = -2
