Answer:
Sean's collection was 250 times greater than Jeremy's.
Step-by-step explanation:
1.0 x 10^7 is the same as 10,000,000
4.0 x 10^4 is the same as 40,000
Divide 10,000,000 by 40,000 to get the answer. 10,000,000/40,000 = 250
2.5+7.5+-10n+-20
Multiply everything on the inside by the number on the outside and put it together with addition signs.
-2.5(-3+4n+8)
-2.5*-3=7.5
-2.5(7.5+4n+8)
-2.5*4= -10
-2.5(7.5+-10n+8)
-2.5*8=-20
-2.5+7.5+-10n+-20
