diameter=d\\
r=radius=\frac{d}{2}\\
----------\\
C=78.5\\
\end{cases}
\\\\\\
 78.5=2\pi r\implies 78.5=2\pi \cdot \cfrac{d}{2}

solve for "d"

Alexxx [7]

Answer:

y=(5/3)x

Step-by-step explanation:

Since y varies directly with x, then the constant of proportionality is equal to k=y/x. Since y/x=20/12=5/3, then k=5/3. This means the equation to relate x and y is y=(5/3)x

Solve this inequality (show your work)<br> 30x+ 600 ≥ 1,500
12345 [234]

Answer:

x ≥ 30

Step-by-step explanation:

30*30 = 900 and when we add 600 to that, we get 1,500 which is the lowest possible number for the left side of the equation to equal. If x equals anything above 30, then it will automatically equal a number greater than 1,500 when added to 600.

(sorry this is confusing, I'm not very good at explaining things. I hope it helped anyway)
