We'll let x represent the weight of Ian's dog.

So we can make the formula Ian's dog (x) + Stephen' dog (5x) = 72

So:
 x+5x=72
6x=72
x=12

So ian's dog is 12 pounds, but we're trying to find stephen's dog (5x)

We need to multiply x by 5 so:

5(12)=60

Therefore, Stephen's dog is 60 pounds

If x was Ian's dog, you could then out it into an equation, looking like :
x + 5x = 72
Then you would simplify:
6x = 72
And then you can solve
6x = 72
÷ 6
x = 12
Now we know that Ian's dog is 12 pounds, if we multiply 12 by 5 we get Stephen's dog, which is 60 pounds. Hope this helps!

How to round 47,125 to the nearest ten,to the nearest hundred, to the nearest thousand and to the nearest ten thousand
Tasya [4]
To be able to round the number 47,125 to the nearest tenth, hundredth, and thousandth place you need to know were those places are. The tens place is the second one from the right hand side. The hundreds place is the third one from the right hand side and the thousands place is the one right after the comma. Now, to round to the tens place, you need to look at the place right behind it (which would be the ones place) then you need to analyze. If the number in the ones place is between 0-4 you can NOT round the tens place but, if it is between 5-9 you can. The same rule applies when you round to the hundreds and thousands place. So the number you should end up with is - 47,135.
