Your answer would be D) 3x + 6
This is because, when you subtract the like terms, you get x - -2x, which is 3x, and 1 - -5, which is 6.
I hope this helps!
Answer:
Simplifying
6x + -2y = 30
Solving
6x + -2y = 30
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
6x + -2y + 2y = 30 + 2y
Combine like terms: -2y + 2y = 0
6x + 0 = 30 + 2y
6x = 30 + 2y
Divide each side by '6'.
x = 5 + 0.3333333333y
Simplifying
x = 5 + 0.3333333333y
Step-by-step explanation:
Circumference = 2 x pi x radius
2 x pi x 4 = 25.13 yards
(correct to 2 decimal places)
