Orders are a, b, c, lets write equations to represent the problem's info:
a + b = 150
b + c = 100
a + c = 150
so we have 3 unknowns and 3 equations, so we can solve.
<span>Use the first equation:
a + b = 150
</span>a = 150 - b
and substitute in the 3rd:
<span>a + c = 150
</span>150 - b + c = 150
then
b = c
and we can substitute that in the original equation:
<span>b + c = 100
</span>2b = 100
b = 50
c = 50
and substitute in the first equation:
<span>a + b = 150
</span>a = 150 - b = 150 - 50
a = 100
then a = 100, b = c = 50

It would be 13 because 12/152 is 12.667 so you round it up
It will take Adrian 4 days to jog 3 miles
Step-by-step explanation:
19 m = 0.019 km
28 m = 0.028 km
686 m = 0.686 km
75 km 6 m = 75.006 km
8282 m = 8.282 km
