The answer is C
Start by making two equations with the given information
The first would just be their total cans:
E + A = 257
The second would be:
5E - A = 13
Then combine the equations to eliminate one variable.
6E = 270
E = 45
Now plug E back into one of the equations.
45 + A = 257
A = 212
[1.4.7.] <span>is a subset because EVERY number in the set I just wrote can be found in the original set given. now if i write [1,49,7] it would not be cause it was not given in the original set</span><span />
They should still be 280 miles apart on the map i belive.
First you do 53+21 =74 and then you will subtract 21 bicycle and tricycles by 74 the total. You should get 53. That's how you check the answer it is 74.
