I don't know what the question is, and I'm guessing that you don't either. All I see here is two statements that disagree with each other. If 7w=87. then w is not 12. And if w=12 then. 7w is not 87.
Answer:
-4x^5+20x^4-40x^3+40x^2-20x+4
Step-by-step explanation:
I think it is 17.50 because if you multiply $.50 by 7 you get $3.50. Then you multiply $3.50 by the 5 days to get $17.50
Answer:
616.788
OR
616.79 (rounded answer)
Step-by-step explanation:
|a| = b gives
a =b or a = -b
so,
|-x| = -10
gives
-x = -10 or -x = 10
x = 10, -10
now let us verify,
when x = 10, |-10| = +10 and it is not = -10
so, x= 10 is NOT a solution.
when x = -10, |-(-10)| = |10| = 10 and it is not = -10
so, x= -10 is NOT a solution.
hence, this equation does not have a solution.
If we know that |...| can never be negative, we can directly deduce that this equation does not have any solution.
