When
you add 6 to the product of a number and 10, the result is 36. What is the number?

20

Step-by-step explanation:

6+(n+10)=36

n=20

6+(20+10)=36

36=36

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
