a+b=350 => a=350 - b
3a + 5b = 1450
3(350-b)+b=1450
1050-3b+5b=1450
2b=400
b=200
a=150
8 units
Circumference = pi * 2 * radius
50.24 = 3.14 * 2 * radius
50.24 = 6.28 * radius
8 = radius
C is the answer I believe
Hoped it helped
Answer:
no it's not parallel to that.
2/3 = x/(3x + y)
2*(3x + y) = 3*x
2*3x + 2*y = 3x
6x + 2y = 3x
6x - 3x = - 2y
3x = -2y
x/y = -2/3
x : y = -2/3.
