The value of y varies directly with x. When y = 3.5, x = 2. What is the value of y when x is 16?

1 answer:

4 0

In order to do this problem, you have to divide 16 by 2 to see how many times x was multiplied. you would find that x was multiplied 8 times, so in order to find y, you would multiply 3.5 eight times.

y = 28 when x = 16

Answer:

$6 \frac{3}{8}$

Step-by-step explanation:

Let's start by turning 8 1/2 into an improper fraction, which would be 17/2. To find the amount of cups needed for a cake that is 3/4 of a full cake, we multiply 17/2 by 3/4.

$\frac{17}{2} *\frac{3}{4} = \frac{17*3}{2*4} = \frac{51}{8}$
