Ronald is setting up an aquarium in his new office. at one pet store, fish cost $2 each and an aquarium cost $40. at another pet store, fish cost $3 each and an aquarium cost $36. write and solve a system of equations to represent the cost of x fish and an aquarium at each store. solve this the system. what does this solution represent? if ronald wants 5 fish, from which pet store should he buy his aquarium

Store #1 : 2x + 40

Store #2 : 3x + 36

he should buy his aquarium from store #1 because (2 * 5) + 40 = 50 and     (3 * 5) + 36 = 51, therefore it is cheaper at store #2 if he is buying 5 fish

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
