Answer:
40.5 g
Step-by-step explanation:
Find how much salt is in 450 g of a 9% salt solution.
Note that
450 g - 100%,
x g - 9%,
then

If you evaporated all water from this solution, then you would get 40.5 g of salt.
Answer:
The Latin phrase is "reduction ad absurd um", meaning reduction to absurdity. You assume the opposite and show that logically it leads to a contradiction and therefore cannot be true.
Hope this helps.
A − 3b = 16
a = b − 2
b - 2 - 3b = 16
2b = - 18
b = - 9
a = - 9 - 2
a = - 11
(-11,-9)
