58.

150 tissues fill 3x2=6 square feet

They want to fill 8x7=56 square feet

The total number of tissues is

$\dfrac{150 \textrm{ tissues}}{6 \textrm{ square feet}} \times 56 \textrm{ square feet} = 1400 \textrm{ tissues}$

59.

$\dfrac{15 \textrm{ seconds}}{1 \textrm{ foot}} \times 1 \textrm{ mile} \times \dfrac{5280 \textrm{ feet}}{\textrm{mile}} \times \dfrac{\textrm{hour}}{3600 \textrm{ seconds}} = 22 \textrm{ hours}$

Answer:

y = $\frac{2}{3}$ x+ $\frac{13}{3}$

Step-by-step explanation:

Okay, the first thing to do here is calculate something known as the "slope".

We know two points are ( 1 , 5 ) and ( − 2 , 3 )

The slope is represented by "m" in the standard form: y = mx+b

The slope is also known as the rise over the run, y2-y1/x2-x1 = $\frac{3-5}{-2-1}$ = $\frac{2}{3}$

=> the standard form: y = $\frac{2}{3}$ x+b

Now we have to use the slope, and resubstitute another point to get b

5 = $\frac{2}{3}$ (1) + b

<=> b= 5- $\frac{2}{3}$ = $\frac{13}{3}$

So the equation that model the line is: y = $\frac{2}{3}$ x+ $\frac{13}{3}$
