Answer:
x=4
Step-by-step explanation:
distribute 5 into (12+5x)
60+25x=20+35x
subtract 35x on both sides
60+25x-35x=20
60-10x=20
subtract 60 on both sides
-10x=-40
divide both sides by -10
x=4

Answer:
Width = 38.57cm
Step-by-step explanation:
Perimeter = 270cm
Let x be the width, so
Length = 2 1/2 x = 5x/2
Perimeter of Rectangle = 2(length + width)
270cm = 2(5x/2 + x)
270 = 5x + 2x
7x = 270
x = 38.571 cm
Therefore, the width is 38.57cm (rounded to 2nd decimal place)
