Answer:

x=6-2y

Step-by-step explanation:

3x+6y=18

Subtract 6y from both sides of the equation.

3x=18−6y

Divide each term by 3 and simplify.

Divide each term in 3x=18−6y.

3x/3=18/3+−6y/3

Cancel the common factor of 3.

x=18/3+−6y/3

Simplify each term.

x=6−2y

Hope this helps! Plz mark as brainliest! :)

Answer:

diameter = 2.5 feet

Step-by-step explanation:

Circumference of a circle is given as C = πd

Circumference of the tree trunk = 7.85 ft

π = 3.14

Diameter of the tree trunk = d

Thus:

7.85 = 3.14*d

Divide both sides by 3.14

7.85/3.14 = 3.14*d/3.14

2.5 = d

d = 2.5 ft
