If you would like to solve the system of equations x + y = 3 and 2x - y = 6, you can do this using the following steps:
<span>x + y = 3 ... y = 3 - x
2x - y = 6
</span>_________
<span>2x - y = 6
</span>2x - (3 - x) = 6
2x - 3 + x = 6
3x = 6 + 3
3x = 9 /3
x = 9/3
x = 3
<span>y = 3 - x = 3 - 3 = 0
</span>
The correct result would be x = 3.

Answer:
3.05 yards
Step-by-step explanation:
Arc length= 2π(r)(Θ/360)
given: 7 yards is diameter, 50 degrees
radius= diameter/2 = 3.5
plug in
2π(3.5)(50/360) = 3.05 yards
