8x+10-2= 2x+44
8x+8= 2x+44
8x-2x= 44-8
6x= 36
x= 6
so A is the correct answer :)
        
                    
             
        
        
        
Answer:

Time for bacteria count reaching 8019: t = 2.543 hours
Step-by-step explanation:
To find the composite function N(T(t)), we just need to use the value of T(t) for each T in the function N(T). So we have that:




Now, to find the time when the bacteria count reaches 8019, we just need to use N(T(t)) = 8019 and then find the value of t:


Solving this quadratic equation, we have that t = 2.543 hours, so that is the time needed to the bacteria count reaching 8019.

Answer:
Ann drove 312 miles in 8 gallons.
Step-by-step explanation:
Distance covered by Ann's car = 117 miles
Gallons of gas spent by Ann's car to cover 117 miles = 3 gallons
Unit rate = 117 miles / 3 gallons
                = 39 miles per gallon
so Ann's car can go 39 miles in one gallon of gas.
- Given that Ann used 8 gallons of gas.
Therefore, 
Distance covered by Ann's car in 8 gallons = 39 × 8
                                                                          = 312 miles
Therefore, Ann drove 312 miles in 8 gallons.
