3d - e =7
d + e = 5
-------------
4d / = 12
d=12:4
d=3
3+e=5
e=5-3
e=2
the solution is (3,2)
The answer is
the option A
<span>The graph shows the solution of the system of inequalities
y> -3
y<=-x
using a graph tool
see the attached figure</span>
The answer is 4.5 hours.
120 miles/2 hours = 60 mph
270-120 = 150 miles
150 miles/60 mph = 2.5 hrs
2 hrs+2.5 hrs = 4.5 hours for the whole trip
