Answer: Tara earned $775 from her summer job.
Step-by-step explanation:
Let x represent the amount of money that Tara earned from her summer job.
Lewis earned $1800 from his summer job at the grocery store. This is $250 more than twice what his friend Tara earned. The equation would be
2x + 250 = 1800
Subtracting 250 from the left hand side and the right hand side of the equation, it becomes
2x + 250 - 250 = 1800 - 250
2x = 1550
Dividing the left hand side and the right hand side of the equation by 2, it becomes
2x/2 = 1550/2
x = 775
Answer:
Because they aren't equivalent. Prolog allows the definition of symbols as inline operators using the op/3 predicate, which allows one to convert arbitrary compounds to formulae and back again.
Step-by-step explanation:
Since 2+2 is a compound with arity 2 and 4 is just an atom unification is impossible and the query fails. To actually do arithmetic equivalence you must use =:=/2 (2 + 2 =:= 4). To solve arithmetic problems you must use is/2 or use an interpreter with arithmetic constraint extensions.Yes, the moment you begin to tie math to real world items, it can turn false very quickly. For example:
(2 red balls + 2 blue balls = 4 orange balls) = false
(2 women + 2 women = 4 men) = false
(2 cats + 2 mice = 4 dogs) = false
(2 oxygen as a single molecule (o₂) + 2 oxygen as a single molecule (o₂) = 4 oxygen as a single molecule (0₄)) = false
That is to say, in the real world there is often non-numerical 'metadata' in additional to the numbers being added, such that a perfect equality (beyond mere quantity) is false. This 'metadata' would include everything from size, to composition, to structure, to color, to temperature, to species, to intelligence, to flavor, to temperament, to physical laws of union and relation, and many other properties.
