Where is the question?
d=vt
d=10(24/60)=4 miles
It is 4 miles to the gift store.
4mi(hr/30mi)(60min/hr)=8 min
It took him 8 minutes on the return trip, for a round-trip time of 32 minutes.
His average speed was (8mi/32min)(60min/hr)=15mph for the whole trip.
1*5=12.75
2*4=9.6
so nine pens cost 3.15
one pen will be 0.35$
so one pencil will be .20$
Answer:
dr. potter provides 54 vaccinations TOTAL (including both measles and polio).
p+m=54
since there are 4 doses of polio and of measles, you have to use a variable to distinguish how many doses were given for measles and polio out of 142 given doses.
4p+2m=142
p+m=54
4p+2m=142
^^system of equation
p+m=54
4p+2m=142
p=54-m
4p+2m=142
(substitute 54-m to the equation)
4(54-m)+2m=142
m=37
(collect like terms, then substitute the value of m into the first equation)
p=54-37
p=17
(m, p)=(37, 17)
