27ex+5) = 22 +5x - 3x
tox +10 = 22+ 2x
6x+10-2x = 22+2x-2x
4x+10 - 22
4x+10-10 : 22-10
4x - 12
x = 3
which of the following properties did he use? check all that apply.

1+1=22×1=22-1=11-1=1duh

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
