3y - x = a
To solve for y we isolate the y variable.
3y = x + a
y = (x + a)/3
Answer:
C.
Step-by-step explanation:
Area of a Sector Formula: A = x/360πr²
Since we are given <em>x</em> and <em>r</em>, simply plug it in:
A = 40/360π(4)²
A = 1/9π(16)
A = 16π/9
Data Input
785 miles every 10 minutes
Procedure:

The answer would be 2747.5 miles
We are given with two equations 2x − 3y = −1 and <span>11x − 9y = −13. The problem says that when the first equation is multiplied by -3 which results to -6x + 9y = 3, the sum of the resulting equation and the second one is equal to 5x = -10. We verify this: -6x + 11x = 5x while -9 y and 9 y cancels out. 3+-13 equals -10. Hence the total is really 5x = - 10.</span>
