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

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

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.

5x10^11 x 65

325 x 10^11

or

325,

$2.97 i think
