Angie takes a ferry ride with her niece. the cost of a ticket for an adult (angie) is three dollars more than the cost of the ticket for a child (her niece). if the cost of an adult ticket is x dollars, which expression gives the total cost of the tickets for angie and her niece?

The cost of Angie's ticket is x, so the cost of her niece's ticket is

x − 3. The total cost for their tickets is x + x − 3, which can be simplified as 2x − 3.

Step-by-step explanation:

the explanation is on top with the answer

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
