Answer:
A is correct answer
Step-by-step explanation:
If you add the two b's then it would be "2b" which is equivalent to the the other problem on the other side of the equal sign which is 2b + 3c
The answer is D: An account earning interest compounded daily.
Exact form (4+11\sqrt(2))/(2)
decimal form 9.77617459
Travel time when Carlos traveled at 52 miles/hr = t1
Travel distance when Carlos traveled at 52 <span>miles/hr = 52 t1
</span>
Travel time when Maria traveled at 54 <span>miles/hr = t2
</span>Travel distance when Maria traveled at 54 miles/hr = 54 t2
total time
t1 + t2 = 4.1
total distance
52 t1 + 54 t2 = 217
<span>( t1 + t2 = 4.1 ) * 52
</span>52 t1 + 52 t2 = 213.2
Subtract last 2 equations
2 t2 = (217-213.2)
2 t2 = 3.8
t2 = 1.9
t1 = 2.2
Hours Maria driven = 2.2 hours
