The opposite of something means to change this signed that is with the number.
If it is a positive number, the opposite would be negative.
So in this example, if it's the opposite of positive 5, that is -5. The opposite of -5 would be positive 5.
The equation that shows this correctly would be D.

Answer:
8 x 2.48 = 19.84
Step-by-step explanation:
We need to find the product for the expression 8 x 2.48.
First no is 8 and second no is 2.48
Product means to multiply.
We can write 2.48 as 
i.e.
Now, apply decimal after 9. So,
8 x 2.48 = 19.84
Hence, the correct option is (b).
I think it’s going to be D
So set both equations equal to each other then solve out of x and plug it back into the x equation to find the angles so start with x+5=2x+10 then subtract x from 2x and you will have 1x then subtract 10 from 5 leaving you with negative 5 then x equals negative 5 and then plug it back into the equation so for example 2 times negative 5 equals negative 10 plus positive 10 equals 0 so therefore x equals 0
