There is one solution, (0,4) is your answer
Note that x = 0, y = 4
(4) = 1/3(0) + 4
4 = 0 + 4
4 = 4 (true)
3(4) - (0) = 12
12 - 0 = 12
12 = 12 (true)
There is one solution, (0,4) is your answer

Answer:
Im guessing you meant it takes 1/3 cups of flour to make 1/4 of a cake not "14"
Step-by-step explanation:
in that case you would do
1/3+1/3+1/3+1/3
or 1/3*4
which would be 4/3
or
1 1/3
Answer:
$225 of birthday money
Step-by-step explanation:
he spent 20 percent (1/5) of the money on dog treats, and the remaining 80 percent (4/5) went to 3 different charities. If $60 dollars were given to each charity, that means a total of $180 dollars was given to charity. if 4/5 of the money is equal to $180, we can divide 180 by 4 to get $45 dollars. this means that 1/5 of the birthday money would be equal to $45 dollars. so to find 5/5, or 100% of the money, simply multiply $45 by the denominator, 5, to get the answer. the total birthday money received was $225 dollars, and $45 dollars of that was used for dog treats.
