First one:
You take 10 + 3 =13 then add 9 then 5. That all equals 27. Then you add 1 for the top part that isn’t labeled because it’s 10 in the bottom then 9 at the top which means it’s 1. Then for the side that’s unlabeled it’s 2 since it’s all 5 then the other side is 3. Answer is 31

Second one:

This one is the same as #1. You add 14+6+3+4 = 27. The long horizontal unlabeled side is 11 bc 14-3 = 11. Then the other side 2. Answer is 30.

Additive inverse of 400

Goshia [24]

Given:

A number is 400.

To find:

The additive inverse of 400.

Solution:

We know that the sum of a number and its additive inverse is 0.

If "a" is number and "b" is its additive inverse, then

$a+b=0$

Let x be the additive inverse of 400. Then,

$400+x=0$

Subtract both sides by 400.

$400+x-400=0-400$

$x=-400$

Therefore, the additive inverse of 400 is $-400$ .

Without solving, explain how you can tell whether the solution to 0.5x = 10 is less than 1 or greater than 1

NemiM [27]

Greater than 1 because left side is a fraction less than 1 and right side is a number greater than 1.

The left side being a fraction less than 1 could only mean that you have to multiply a number greater than 1 to the other side. And since the other side is a number greater already than 1 then multiplying the left side to the right side must result in a number greater than 1.
