What integer multiplied by 8 equals -96?
Gwar [14]

Answer:

-12

Step-by-step explanation:

Let "integer" = x

When x is multiplied by 8, it equals -96:

8x = -96

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Divide 8 from both sides

(8x)/8 = (-96)/8

x = -96/8

x = -12

-12 is your answer

800-675, why do we borrow?
Stolb23 [73]
When doing vertical subtraction, 800 - 675 will turn out like this:
  800
- <u>675

</u><u>
</u>You should know that we start on the right and then end on the left.
<u>
</u>So, we do 0 - 5, 0 - 7, then 8 - 6, right?
No. We have to borrow because you can't have a negative number when doing each number individually, only until the end. In this case, there won't be any negative numbers.
<u>
</u>You can't do 0 - 5 or 0 - 7, so you have to borrow, changing the number to the left of it one lower (unless it's 0, so then you must borrow the the next number after that).<u>
</u>
