Answer:
Step-by-step explanation:
A direct variation equation is of the form
y = kx,
where, in words, it reads "y varies directly with x" or "y varies directly as x". In order to use this as a model, we have to have enough information to solve for k, the constant of variation. The constant of variation is kind of like the slope in a straight line. It rises or falls at a steady level; it is the rate of change.
We have that a vet gives a dose of three-fifths mg to a 30 pound dog. If the dose varies directly with the weight of the dog, then our equation is
d = kw and we need to find k in order to have the model for dosing the animals.
Divide both sides by 1/30 to get k alone.
and
Our model then is
This means that for every pound of weight, the dog will get one-fiftieth of a mg of medicine.
A fraction can be viewed as a division problem, and a mixed number can be viewed as an addition problem. So,
7 29/80 can be read as:
7+29÷80
Follow the order of operations and you'll have your decimal.
7+29÷80
7+0.3625
7.3625
Answer:
y=20x+150
Step-by-step explanation:
Sandy has 150 dollars ALREADY in her account, so each time she earns the money it is building upon. 20x (x because we don't know for how many months.)
