Answer:

x = -9

Step-by-step explanation:

The attachment shows the labeling according to the problem statement.

The overall length is the sum of the constituent segment lengths, so ...

FG + GH = FH

(10 +x) +(7) = (2x +26)

x +17 = 2x +26

x -9 = 2x

-9 = x

<em>Check</em>

Then the segment length FG is ...

10 +x = 10 -9 = 1

and the overall length is ...

2x +26 = 2(-9) +26 = -18 +26 = 8

That is, 1 + 7 = 8.

Solve the formula C = πd for d

REY [17]

Answer:

$d = \frac{C}{\pi}$

Step-by-step explanation:

$C= \pi d\\$

Isolate d ; Divide both sides of the equation by $\pi$

$\frac{C}{\pi} = \frac{\pi d}{\pi }$

Simplify

$\frac{C}{\pi} = d\\\\d = \frac{C}{\pi}$

Note; Another formula for d(diameter) =

$2\times radius$
