8 - 4 = 7 - 3 because it has a equal sign in the middle meaning that you have to find an equation that’s equal to it. So thats why the missing number is 3
3 are you serious? If you are, here’s the explanation: It’s like finding x 8-4=7-x Let’s simplify it, we know that 8-4=4 4=7-x Now, we wanna get x by itself, since that’s what we’re looking for. Go ahead & get rid of 7. Since 7 is a positive number, well subtract it. Also, remember that what we do on one side, we must do to the other side, so subtract 7 on BOTH sides 4-7=-x Simplify. -3=-x Now, we need x to be positive, so let’s get rid of the negative sign (-). We’ll do this by dividing -1 on BOTH sides. 3=x ——> x=3 Hope this helps! :)
Well, this is easy and rather basic in my opinion. If you open a calculator and multiply 79.924 by 24, you come out with 1,902.96 grams. If you wanted to convert it into pounds, it would be 4 pounds.
