It is true.
The results may no longer be valid, but that is not relevant to the question that was asked.
That is true because in addition the number only comes up once.
When you put together unequal groups you only add. Is he correct?
juan says when you put together unequal groups you can only add is he correct
Yes, that's true. Basically you can multiply and divide them; but you can't add, subtract, or compare them.
To add scalar quantities, simply add the numerical values together. Scalars are quantities that only have a magnitude and no direction, such as mass or temperature. There is no need to consider any specific direction when adding scalar quantities.
No.
No.
Yes
7 > 1 this true. 7 - 5 > 1 - 5 2 > - 4 this also is true (remember, numbers grow up from the left to the right in a number line).
Just add 25 to both sides of the inequality - that way, you will isolate the "x", i.e., solve for "x".
Mainly because they aren't scalar quantities. A vector in the plane has two components, an x-component and a y-component. If you have the x and y components for each vector, you can add them separately. This is very similar to the addition of scalar quantities; what you can't add directly, of course, is their lengths. Similarly, a vector in space has three components; you can add each of the components separately.
