In which number does the digit 3 have a value 10 times greater than in the number 3,000

The number 3 is in the thousands position so if you need to know what position is 10x the 3’s position, it would be 3,000 x 10 = 30,000 so it would be the ten thousandths position.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
