Use the expression for y in the second equation.
.. 3x +4(3 -(1/2)x) = 1
.. 3x +12 -2x = 1
.. x +12 = 1
.. x = -11

<h3>Answer:</h3>

133 ft

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

Given in the question,

length of the rectangle = 31 ft

width of the rectangle= 20 ft

diameter of semicircle = 20 ft

radius of semicircle = 20/2 ft = 10 ft

<h3>Formula to use:</h3>

perimeter of rectangle + perimeter of semicircle

perimeter of rectangle = 2(l+w)

perimeter of semicircle = 1/2(2πr)

<h3>Plug values in the formula above</h3>

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:

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