From the set {36, 16, 13}, use substitution to determine which value of x makes the equation true. 3x = 39

Step-by-step explanation:

3x = 39so instead of just subbing in all ur answer choicesjust solve for x

3x = 39...divide both sides by 3, cancelling out the 3 on the left side

x = 39/3

x = 13 <

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
