She wanted to stop at the palace for tea and asked the cab to wait for her. The cost of waiting is 2 krona per hour. The cost of the tea was 25 krona. Maria was at the palace for two hours. She also shopped at the gift shop and spent 50 krona. Write an algebraic expression to determine the total cost of Maria’s excursion to the Royal palace in Stockholm, Sweden.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5
