Answer:

(\frac{3^{-1}+2^{-1}}{5^{-1}})^{-1}+3=\frac{81}{25}

Step-by-step explanation:

Given expression is,

(\frac{3^{-1}+2^{-1}}{5^{-1}})^{-1}+3

By solving the given expression,

(\frac{3^{-1}+2^{-1}}{5^{-1}})^{-1}+3=(\frac{\frac{1}{3}+\frac{1}{2}}{\frac{1}{5}})^{-1}+3

                     =(\frac{\frac{2+3}{6}}{\frac{1}{5}})^{-1}+3

                     =(\frac{\frac{5}{6}}{\frac{1}{5}})^{-1}+3

                     =(\frac{5}{6}\times \frac{5}{1})^{-1}+3

                     =(\frac{25}{6})^{-1}+3

                     =\frac{6}{25}+3

                     =\frac{6+(25\times 3)}{25}

                     =\frac{81}{25}

4. The length of a rectangle is 4 more than its width. The perimeter of the rectangle is 60cm.
sergey [27]

Step-by-step explanation:

let width = w

if width = w, then length = w + 4

Therefore the perimeter is 2w + 2(w+4)

2w + 2(w+4) = 4w + 8

perimeter = 60cm

4w + 8 = 60

<em>-8</em>

4w       = 52

<em>divide each side by 4</em>

w = 13

length = w+4

therefore, length = 17

At noon joyce drove to the lake at 30 mph, but she made the long walk back home at 4 mph. how many hours did she walk if she was
lina2011 [118]
By definition we have the following equation:
 t = d / v
 Where,
 t: time
 d: distance
 v: speed
 For this case we have:
 d / 30 + d / 4 = 17
 Rewriting we have:
 2d + 15d = 17 (60)
 17d = 17 (60)
 d = 60 mi
 Then, the walking time is
 t = d / v
 t = 60/4
 t = 15 hours
 Answer:
 
She walked
 
t = 15 hours
