Y varies directly as xy equals 5 when X is 8 how do you find y when X is 9
FrozenT [24]

Given, y varies directly as x

So,

y=c\cdot x

Where c is a constant

When y equals 5 when x is 8

So,

\begin{gathered} 5=c\cdot8 \\ c=\frac{5}{8} \\  \end{gathered}

So, the relation between y and x

y=\frac{5}{8}x

now , when x = 9

Substitute with x to find y

y=\frac{5}{8}\cdot9=\frac{45}{8}

So, the answer is option 2. y = 45/8

13) A hexagon has 6 equal sides! Ms. Sears asked the students to find the perimeter if all sides are equal to 2x + y. One studen
mestny [16]

Answer:

None of the answers are right

Step-by-step explanation:

Since a hexagon has 6 sides, and perimeter is the length of all the sides summed up, we can multiply 6 by 2x+y to find the perimeter.

6(2x+y)

Distribute the 6 to each term in the parentheses:

6(2x)+6(y)

12x+6y is the perimeter. None of the answers are right.
