Answer:
Step-by-step explanation:
MR=2x-1. First equation
RP=9x+3 second equation
MP=MR+RP third equation
MP= 2x-1+9x+3 first equation plus second equation
MP=11x+2
MP=57
57=11x+2 replaced MP value
57-2=11x
55=11x
55/11=x
X=5

The exact distance she drove was 236.39 miles
61.4 miles per hour x (times) 3.85 hours = 236.39 miles in total
P is the cost of a pound of peanuts and F is the cost of a pound of dried fruit
0.5p+0.75f=6.5
0.75p+0.25f=4.5
Rearrange
0.5p=-0.75f+6.5
Simplify
P=-1.25f+13
Substitute
0.75(-1.25f+13)+0.25f=4.5
simplify
-0.9375f+9.75+0.25f=4.5
<span>-0.6875f+9.75=4.5
</span>-0.6875f=-5.25
f=7.636364
Round
F=$<span>7.64 per pound
</span>
Plug in
0.75p+0.25(7.64)=4.5
Simplify
0.75p+<span>1.91=4.5
0.75p=</span><span>2.59
</span>p=3.453333
Round
P=$3.45 per pound of peanuts
Final
P=$3.45 per pound of peanuts
F=$7.64 per pound of dried fruit
