Step-by-step explanation:
- 90 + (x + 5) + (2x - 2) = 180
- x + 5 + 2x - 2 = 180 - 90
- 3x + 3 = 90
- 3x = 87
- x = 29
 
        
                    
             
        
        
        
The way to answer this question is to first make 52% into a decimal:
52% = 0.52
so now we will simply multiply:
   84
x.52
once you have multiplied these numbers it comes out to be 43.68.
So your answer is 43.68.

Answer:
Give brainliest please! The answer is 53.2 mph
Step-by-step explanation:
Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m.
1:40 p.m. is 13:40.
Thus, they traveled for
13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes
that is  hours.
Use formula:
where
D = distance
r = rate
t = time.
In your case,
D = 239.4 miles
t = 4.5 hours
