Step-by-step explanation:
Add '-16y' to each side of the equation.
12x + 16y + -16y = 6 + -16y
Combine like terms: 16y + -16y = 0
12x + 0 = 6 + -16y
12x = 6 + -16y
Divide each side by '12'.
x = 0.5 + -1.3...y
Simplifying
x = 0.5 + -1.3...y
Step-by-step explanation:
since it is a circle the diameter is two times larger than radius.So 4×2=8km
The maximum number of shrubs (x) = a(area) divided by 15.9
a(area)=37.1*15
37.1*15= 556.5
556.5/15.9=x
556.5/15.9=35
35=x
