2 less than (3 times a number) is the same as (the number plus 10)
2 less than (3*x) = (x + 10)
3x - 2 = x + 10
From here, you solve! :)
3x - 2 - x = x + 10 - x
2x - 2 = 10
2x - 2 + 2 = 10 + 2
2x = 12
2x / 2 = 12 / 2
x = 6
Hope this helps! :)
        
             
        
        
        
Answer: 52,416,000 km
Step-by-step explanation:
If a comet travels 273,000 km/hr
1) Multiply 273,000 km by 24 hours to find how far the comet travels in one day
2) multiply the answer from 1 by 8 to determine how far it travels in 8 days
 1)  *
* =
 =  (hours cancel out)
 (hours cancel out)
2) *8 day= 52,416,000 km in 8 days
*8 day= 52,416,000 km in 8 days
The comet approximately travelled 52,416,000km from when it began to travel to when it reached Earth. Hope this helped :)

X is 90 i think because it shows you the right angle
        
                    
             
        
        
        
Imaginary numbers are taught in high school algebra, which I think imaginary numbers are taught in 10th or 11th grade.
