Answer:
54 km
Step-by-step explanation:
The distance she covers would be equal to twice the perimeter of the park which is in the shape of a rectangle
perimeter of a rectangle = 2 x (length x width)
length = 4.5
width = 2 x 4.5 = 9
2 x (4.5 + 9) = 27km
In one walk, she covers a distance of 27km. In two walks, she covers a total distance of 27km x 2 = 54km
Answer: My teacher told me to use 180 and divide something.
Step-by-step explanation:
Answer:
the first one to solve for x is x=22-y
the first one to solve for y is y=22-x
the second one to solve for x is x=6+y
the second one to solve for y is y=-6+x
Step-by-step explanation:
in the first two you had to subtract y from both sides of the equation
the second one you had to add y to both sides of the equation to solve for x
but to solve for y you have to move all terms that dont contain y to the right side and solve
