Write a problem in words that can represent this equation: 13x + 26 = 91

Ellie wants to buy perfumes and each are $13 and she has a candle in her cart that is $26. How many bottles of perfume can she buy if she only has $91?

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
