OLEGan [10]

<h2>Explanation:</h2>

The complete question is in a comment above. The statements says that:

Sean wrote the equation $9.25=5m$
$m$ is the cost per pound.
The equation show the relationships between the total cost, $9.25, and the number of pounds of pears.

So we are asked to write an write an equation to show the cost y of x pounds of pears. In other words, we need to write an equation such that y is given in terms of x, where x is the pounds of pears. So:

$y=f(x)$

From the equation we can determine $m$ as:

$m=\frac{9.25}{5}=1.85$

So each pound costs $1.85. The equation tells us that 5 pounds of pears result costs $9.25. Then, by proportion:

$\frac{y}{x}=\frac{9.25}{5} \\ \\ y=1.85x$

So choosing the number of pounds as 0, 1, 2, 3, 4, 5, the table would be:

$\begin{array}{cc}x(\text{Number of pounds}) & y(\text{Cost in dollars})\\0 & 0\\1 & 1.85\\2 & 3.7\\3 & 5.55\\4 & 7.4\\5 & 9.25\end{array}$

From the table we can know that the graph is a line. that passes through all these points. Since this line passes through the origin, then y varies directly as x (Direct Proportion).

Sue bought 54 ft of lumber for building a window frame each window frame requires 13 1/2 feet of lumber how many window frames h

Arturiano [62]

Answer:

The correct answer is 4 window frames.

Step-by-step explanation:

Sue bought 54 feet of lumber for building window frame.

Each window frame requires 13 1/2 feet = $\frac{27}{2}$ feet of lumber.

Therefore the number of window frames Sue can make with 54 feet of lumbers she bought is given by dividing the total amount of lumber she has by the lumber it takes to make a single window frame.

= $\frac{54}{27}$ × 2 = 2 × 2 = 4
