4 0

Answer:

x=1, y=2. (1, 2).

Step-by-step explanation:

x-3y=-5

-3x+7y=11

----------------

x=3y+(-5)

x=3y-5

-3(3y-5)+7y=11

-9y+15+7y=11

-2y=11-15

-2y=-4

2y=4

y=4/2

y=2

x-3(2)=-5

x-6=-5

x=-5+6

x=1

community group is planning the expansion of a square flower garden in the city park if each side of the original Garden is incr
JulijaS [17]
4mm
The sides of the new garden can be represented by x+9. x is the original size and 9 is the added 9mm. Multiply the sides to get (x+9)(x+9) or (x+9)^2
this will equal the area. Create an equation to solve for the unknown original length.
169=(x+9)^2
Take the square root of both sides
13=x+9
Subtract both sides by 9
4=x The original side was 4mm long

18 = 12k/(1/3)
18 = 36k
k = 18/36 = 1/2
