x=15
multiply each side by 3/2
x becomes isolated, 10*1.5=15
x=15
Answer:
multiply the radius by 2π
Step-by-step explanation:
The formulas for circumference of a circle is
C = πD where D is the diameter,
or
C = 2πr where r is the radius.
Either formula is correct, but we will work with the second one since the question is asking about radius.
We see that 2π(r) = the circumference, so multiply r by 2π to get the circumference
Question : Jin’s soccer team has 4 coaches and 22 players, and his twin sister’s team has 2 coaches and 11 players. If the relationship between the number of players and coaches is proportional throughout the league, which ordered pair could represent the total number of coaches and players in the entire league?

X + y = -6
x + (3x - 2) = -6
4x -2 = -6
4x = -4
x = -1
y = 3x -2
y = 3 (-1) -2
y = -3 - 2
y = -5
Solution: x= -1, y= -5
