A would be the correct answer because the y variable only has a coefficient of 1. So we would solve for y, which would get us y=3x+5, then we would substitute the value in the second equation which would look like -4x+5(3x+5)=58. Hope this helpss. :)
Answer:
its the first one
Step-by-step explanation:
Check picture below, radius = r = 15, thus
The answer is 376.8 m.
It is given:
radius: r = 60 m
<span>π = 3.14
c = </span><span>π * d
d - diameter.
It is known that diameter is twice of radius:
d = 2r
So, implement it in the formula:
c = </span>π * d = π * 2r = 3.14 * 2 * 60 = 376.8 m
