Answer:
11.27cm
Step-by-step explanation:
705% of 14milimeters
705/100 X 14 = 98.7
increase by adding 98.7milimeter to 14milimeter
98.7+14= 112.7milimeter or 11.27cm
So represent missing number with x
x means unknown so
x+-1=+1
adding a negative means subtraction
x-1=1
you can do anything to an equation as long as you do it to both sides
add 1 to both sides
x+1-1=1+1
x+0=2
x=2
the number is 2
