I think that the answer is A.
Tom wants to save at least $2000. He already got $375. Let x be the amount he still needs to save.
375 + x >= 2000
Subtract 375 from both sides
375 + x - 375 >= 2000 - 375
x >= 1625
So he still needs to save at least $1625.
Hope this helps! :)
First you divide L+W by 2 and you would get A/2=L+W then you would subtract L and get A/2 -L=W
20 - 4 - 2 = 14. A negative number is just like subtracting it.
