Step-by-step explanation:

The word 'rational' in 'rational numbers' comes from the word 'ratio.' That is because rational numbers are those numbers which can be obtained when one integer is divided by another integer. For example, the number 8 is a rational number because it results when the integer 24 is divided by the integer 3, as in the ratio 24/3.

the performing arts department put in its spring show on Friday and Saturday nights. the price of a ticket was the same both nig

Galina-37 [17]

Let $p=$ the price of a ticket
Let $c=$ the cost to put on the show

Formula:
(profit) = (ticket price) * (number of people) - (cost to put on show)
We have two equations here:
$500=120p-c$
$400=100p-c$
Solve:
$100=20p$
⇒ $p=5$
⇒ $400=100(5)-c$
⇒ $400=500-c$
⇒ $c=100$

So the price of a ticket is $5, and the cost to put on the show is $100.

6 cm=48 km

Divide by 6

6 cm/ 6 = 48 km /6

1 cm=8 km
