Answer:
x=−y−3
Step-by-step explanation:
x+y=−3
Step 1: Add -y to both sides.
x+y+−y=−3+−y
x=−y−3
Answer:
x=-11
Step-by-step explanation:
the (x+14) line is half of the (17+x) line, so in order to solve this we would have to set it up like this:
2(x+14)=17+x
distribute
2x+28=17+x
x=-11

Area of a circle is πr².
Therefore we can get the radius of the great circle (and thus the sphere) by doing √(A / <span>π).
</span>
√(28.6 / <span>π) = 3.017 to 3DP.
</span>
Surface area of a sphere is 4πr².
4<span>π(3.017)</span>² = 114.4 to 1DP
