Answer:

Step-by-step explanation:

1 oz = 0.0625 lb

Ratio of the hiker an backpack in the first row = 152.25 lb : 14.5 lb

                                                                            = 21 : 2

Hiker's weight       Backpack weight                  Total weight (in lb)

1). 152 lb 4 oz                14 lb 8 oz                (152+14) lb (4+8) oz = 164lb 12oz

                                                                                                  = 16.75 lb

2). 107 lb 10 oz               10 lb 4 oz                (107+10) lb (10+4) oz = 117 lb 14 oz

                                                                                                        = 117.875 lb

3). 129 lb 15 oz           \frac{129.9375}{x}=\frac{21}{2}                 (129+12) lb (15+6)oz = 141 lb 21 oz

                              x = 12.375 lb                                                      = 142.3125lb

                              x = 12 lb 6 oz

4). \frac{x}{8.75}=\frac{21}{2}                   8 lb 12 oz                 (8 + 91) lb (14+12) oz = 99 lb 26 lb

   x = 91.875 lb                                                                                = 100.625 lb

  x = 91 lb 14 oz

5). \frac{x}{10}=\frac{21}{2}                     10 lb                           (105 + 10) lb = 115 lb

    x = 105 lb

How to find when,<br>y=-1/3x - 3<br>​
Montano1993 [528]
The -3 would be where your line crosses the y-axis, so you would plot your point at -3. your slope will always be counted as rise/run, basically meaning you would count along the y-axis a certain amount of times, in this case -1, and along the x-axis a certain amount of times, here would be three. your next plot point would be (3,-4) and so on. hope this helped!

Keisha the trainer has two solo workout plans that she offers her clients: Plan A and Plan B. Each client does either one or the
gregori [183]

Answer:

Plan A last 0.75 hours or 45 minutes.

Plan B last 1.5 hours or 90 minutes.

Step-by-step explanation:

Let a be the number of hours that the plan A last, an b the number of hours of plan B. Then for the Wednesday you have:

2a+3b=6

And for the Thursday is:

6a+5b=12

Multiply the equation of Wednesday by -3:

-6a-9b=-18

Using the method of addition using this last equation and the equation of Thursday

-6a-9b=-18\\6a+5b=12\\--------\\-4b=-6\\b=\frac{-6}{-4}\\b=1.5 hours

Replacing the value of b in one of the equations

6a+5b=12\\6a+5(1.5)=12\\6a+7.5=12\\6a=12-7.5\\a=\frac{4.5}{6} \\a=0.75hours
