<h3>Answer:</h3>

<h3>Step-by-step explanation:</h3>

Given in the question,

length of the rectangle = 31 ft

2(31 + 20) + 3.14(10)

133.4 ft

≈ 133 ft

Solve for C:<br> Spam: deiodhwidweiudjegydjwe
Maksim231197 [3]

Answer:

C=\frac{5F-160}{9}

Step-by-step explanation:

Let's solve for C.

F=\frac{9C}{5}

Step 1: Flip the equation.

\frac{9}{5} C+32=F

Step 2: Add -32 to both sides.

\frac{9}{5} C+32+-32=F+-32

\frac{9}{5}C=F-32

Step 3: Divide both sides by \frac{9}{5}.

\frac{\frac{9}{5}C}{\frac {9} {5}}=\frac{F-32}{\frac{9}{5} }

C=\frac{5F-160}{9}

Answer:

C=\frac{F-160}{9}
