Reptile [31]

Answer:

64

Step-by-step explanation:

First of all substitute the values to where ever you see their corresponding variables to make them multiply.

x = 9

y = 3

z = 2

so we get

8x as 8(9),

7z as 7(2)

2y as 2(3)

then the it's will be

8(9) - 7(2) + 2(3)

which is

72 - 14 + 6

finally we get

64

Greg is volunteering at a track meet. He is in charge of providing the bottled water. Greg knows these facts:
GuDViN [60]

Answer: There are 819 fewer number of cases of water bottle that all athlete, all coaches and all judges will get.

Step-by-step explanation:

Since we have given that

Number of days the meeting is going on = 3 days

Number of athletes = 117

Number of coaches = 7

Number of judges = 4

Number of bottles given to each athlete each day = 4

Total number of bottles total athlete for 3 days will get is given by

117\times 4\times 3\\\\=1404

Number of bottles given to each coach each day = 3

Total number of bottles total coach for 3 days will get is given by

7\times 3\times 3\\\\=63

Number of bottles given to each judge each day = 2

Total number of bottles total judge for 3 days will get is given by

4\times 3\times 2\\\\=24

Number of cases of water bottle is given to athletes is given by

\frac{1404}{24}

Number of cases of water bottle is given to coaches is given by

\frac{63}{24}

Number of cases of water bottle is given to judges is given by

\frac{24}{24}

We need to find the fewer number of cases that all athlete , all coaches and all judges will get

\text{L.C.M. of }\frac{1404}{24},\frac{63}{24},\frac{24}{24}\\\\=\frac{L.C.M.\ of\ 1404,63,24}{H.C.F.\ of\ 24,24,24}\\\\=\frac{19656}{24}\\\\=819

Hence, there are 819 fewer number of cases of water bottle that all athlete, all coaches and all judges will get.
