Answer:

50 cm

Step-by-step explanation:

Circumference = $2\pi r$

$2\pi r$ = 157

$\frac{2* 22 r}{7}$ = 157

r = 157 * 7 / 44

r = 24.97 cm

r can be rounded to 25cm

so the diameter = 50cm

Answer: The correct answer is -x+3y=6

Step-by-step explanation:

Solve for x:

y=1/3x+2

1) Flip the equation:

1/3x+2=y

2) Add -2 to both sides:

1/3x+2+−2=y+−2

1/3x=y−2

3) Divide both sides by 1/3:

(1/3x)/(1/3)=(y−2)/(1/3)

x=3y−6

In standard form (Ax=By=C): -x+3y=6
