For this case we must simplify the following expression:
We apply distributive property to the terms within parentheses:
We add similar terms:
Thus, the simplified expression is: 
Answer:
We know that
<span>Monica can walk 3.8 kilometers in 40 minutes
and
</span><span>she can jog twice that distance in the same amount of time
that means
in 40 minutes Monica can jog (3.8 km*2)-----> 7.6 km
1 hour=60 minutes
</span>by proportion<span>
7.6 km/40 minutes=x km/60 minutes
x=7.6*60/40----> x=11.4 km
the answer is
11.4 km</span>
A+b+c=-44.84
a=26.6
b=c
26.6+b+b=-44.84
2b=-44.84-26.6
b=-35.72
So, a=26.6, b=-35.72, c=-35.72
