Step-by-step explanation:
Step one:
Given
The expression for Katya's distance away from home is given by the expression
y represents her total distance away from home
x= represent the time of travel in hours
Step two:
60 represents the rate at which the train is traveling in km per hour
20 represents the initial distance from home
we predict her distance away at a given time
say 4 hours, that is x=4hours
substituting in the expression
y=60x+20
y=60(4)+20
y=240+20
y=260km
Answer:
The solution to a system of equations means the point must work. In both equations in the system, if you are asked if a point is a solution to an equation, you replace the variables with the given values and see if the two sides of the equation is equal "so is a solution"
15x + 30y = -10....reduce by dividing by 5
3x + 6y = -2...same as first equation...same line ..means infinite solutions
If it was 20 inches x 10 inches the perimeter would be 60 inches. which is the smallest possible perimeter with whole numbers
5 3/4
5 remainder 3
Is the mixed number
