Answer:

METHOD 1:

5x+7(x+1)=5x-21

5x+7x+7=5x-21

12x+7=5x-21

12x-5x=-21-7

7x=-28

x=28/7

x=4

METHOD 2:

5x+7(x+1)=5x-21

5x+7(x+1)=5x-21-5x

7(x+1)=-21

7x+7=-21

7x=-28

x=4

Step-by-step explanation:

METHOD 1:

5x+7(x+1)=5x-21

5x+7x+7=5x-21

12x+7=5x-21

12x-5x=-21-7

7x=-28

x=28/7

x=4

METHOD 2:

5x+7(x+1)=5x-21

5x+7(x+1)=5x-21-5x

7(x+1)=-21

7x+7=-21

7x=-28

x=4

Round 693,856,639 to the nearest thousand.
kogti [31]
Round 693,856,639 to the nearest thousand.How do you that than? Thats a long NUMBER?
Well, I'm going to tell you that if the number is higher than 5 than you round up but if the number is lower 5 you round down. So, how would you do that to find the nearest thousand?  693,856,639 so, you would know where the thousand is right? it's 6,639 lets just cancel the part 693,85  and think about 6,639. As I told you if the number is higher than 5 than you round up but if the number is lower 5 you round down. 
6,639 so now if you look at the right side it's higher than 5 it's a 6 so, if you round up to the nearest thousand it's 7,000
so 6,639=7,000
