Answer: Yes they are like terms
They both have the same variable so that is why they are like terms.
We can think of 'd' representing something like "dogs" maybe
d = 1 dog
2d = 2 dogs
3d = 3 dogs
4d = 4 dogs
and so on
Adding 2d with 4d gets us 2d+4d = 6d meaning we have 6 dogs overall if we started with 2 and added on 4 more. This is one way to help see why we can combine like terms.
In contrast, something like 2c+4d cannot be combined since having 2 cats and 4 dogs doesn't result in 6 cats or 6 dogs. We just simply leave it as 2c+4d.
Answer:
$4
Step-by-step explanation:
Total expenditure is $55
Breakdown
2 books cost $10
4 books cost $25
Subtotal for 6 books is 10+25=$35
Remaining amount from total is 55-35=$20
If each book costs approximately $5 then for $20, each book is 20/5=$4

The lost percentage = 9%
Amount she had = $22,750

As she had lost 9%, it means she will remain with 91% of her investment. Let the original investment is x.
So,
So, her original investment is equal to $25000.
