Whag is the answer to this equation: 13-4x=1-x

Step by step:
1. Get all the x's on one side. Add 4x to both sides
13=1+3x
2. Isolate the x variable. Subtract 1 from both sides
12=3x
3. Solve for x. Divide by 3 on both sides.
x=4 :)

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 )
