Since ΔCDE is isosceles with base angles D and E equal then sides

CE = CD , hence

16x - 27 = 4x + 9 ( subtract 4x from both sides )

12x - 27 = 9 ( add 27 to both sides )

12x = 36 ( divide both sides by 12 )

x = 3

substitute x = 3 into the expressions for the sides

CD = (4 × 3 ) + 9 = 12 + 9 = 21

DE = (7 × 3 ) - 5 = 21 - 5 = 16

CE = (16 × 3 ) - 27 = 48 - 27 = 21

note that CE = CD

The number of decimal places

To do this, we simply calculate the number of digits after the decimal points

$0.47 \to 2\ digits$

$3.2 \to 1\ digit$
