Answer:

Answer in explanation

Step-by-step explanation:

We can use a number line to explain this subtraction.

The first thing to do is to locate the number 7 on the number line. This should be located to the right of the number line.

Then, since we are subtracting, we need to count left from the position of interest. So we will count 12 integers to the left of 7.

If things are right, we would land at -5

If it was a case of addition, we will need to keep counting right from the position of origin

What is the value of   ?
azamat
Sure! So this is ready as "the cube root of 125". This basically means, "what number cubed can get me 125?"
Let's go through our options.
We can rule out D, as D cubed would be unreasonably big.
We can also rule out C, because 375 cubed is easily over 10000, you know this even if you haven't computed it all, just compute the 300 cubed.
We can rule out B, too. 41 squared is already over 125, therefore it can't be the answer.
Therefore our answer is A, 5. We can check that by cubing 5, and that indeed gets us 125.
Hope this helps!
