I need help with #4 asap plsss

5 and 8 are supplementary

3=8 (vertically opposite)

so 5 and 3 are supplementary

also 5 and 6 are supplementary (linear pair)

now we've got

5+3=180°

5+6=180°

3=6

Statement: 5 and 3 are supplementary as 3=8

reason: vertically opposite

statement: 5 and 6 are supplementary

reason: linear pair

statement: 3=6

reason: both are supplementary to a same angle

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
