You start by writing the equation; x + x - 11 = 35
Then you combine like terms giving 2x - 11 = 35
You solve for x resulting in x = 23
So the numbers would be 23 and 12
Answer: 221 years or in the year 2192
Step-by-step explanation: The 13-year locusts emerge after every 13 years, that is, after every year that is a multiple of 13. The 17- year locusts emerge after every 17 years, that is, after every year that is a multiple of 17. Therefor, if both 13- and 17- year locusts happened to emerge in 1971, such interference would repeat after every x years, where x is a common multiple of 13 and 17. The next interference would occur after the number of years which is the least common multiple of 13 and 17.
380% Of 60 Is 60*3.8
That Is Close To 60*4
60*4 Is Also 60*2*2 Which Is Easier
60*2*2=120*2
120*2=240
240 Is A Good Estimate.
