Given 7x/2 < 5 find the soloution set

1. Multiply both sides by 2. 7x/2*2<5*2 aka 7x<10

2. Divide both sides by 7. 7x/7<10/7 aka x<(10/7)

3. Your solution should be x<(10/7) or in decimal form x<1.43...

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
