IrinaK [193]

Answer:

10% of 2,000 is 200. 2000 + 200 = 2200. 10% of 2200 is 220. 2200 + 220 = 2420. Answer is 2420.

Which expression is equivalent to 5st + 40t
Art [367]

Answer: 5(1st+8t)

Step-by-step explanation:You factor 5st + 40t  using GCF .And the GCF of 5 and 40 is 5 .So you take 5st and you divide it by 5 and also you take 40 t and divide it by 5 too.And after you take 5st and you divide it by 5 ,you get 1 st .To add on,after you take 40 t and divide it by 5 you get 8t .Finally ,you take the GCF which is 5 and place  Parentheses next to it and you take 1st and 8t and you add them together .

So your expression that is equivalent to 5st + 40t ,is 5(1st+8t) .

Hope it help :)and You are welcome .
