State whether the following is reasonable or not. Explain your answer. Josefina gave away 130% of her stamp collection.
Nastasia [14]

Answer:

The statement is not reasonable.

Step-by-step explanation:

Josefina gave away 130% of her stamp collection.

We cannot give more than what we have.

lets understand it mathematically.

suppose i have x stamp.

according to question, i have to give 130% of my stamp collection

130% of x = 130/100 x = 1.3x

so, i have to given 1.3x stamp while i do have only x stamp which does not make any sense.

maximum i can give is x stamp.

x stamp in percentage of my total stamp collection which is also x will be

= x/x*100 = 100%

Thus, maximum one can give is 100% of what he has.

Thus, we can say that Josefina gave away 130% of her stamp collection is not reasonable.

The like terms are the numbers with

We can then put the like terms together to continue the calculation:

x+6x+2x+10

=9x + 10

Therefore, the answer is 9x + 10.

Hope it helps!
