(36 3/4" + 36 3/8" + 371/2" +z) /4 = 36 5/8"
This is the equation that you would get for the average. Now we just solve for z.
Following PEMDAS you have to mulitply the equation by 4 to get rid of the divide by 4 part.
4( (36 3/4" + 36 3/8" + 371/2" +z) /4 = 36 5/8)
Which does this
36 3/4" + 36 3/8" + 371/2" +z = 146 1/2"
Now you have to add and subtract to get "z" by itself.
36 3/4" + 36 3/8" + 371/2" = 110 5/8"
(110 5/8" + z = 146 1/2" ) -110 5/8"
z= 35 7/8", so the answer is b
This math is just too much and makes little to no sense.
Umm what is this supposed to mean more information
Answer:
45
Step-by-step explanation:
Given that the number of savory dishes is 9 and the number of sweet dished is 5.
Denoting all the 9 savory dishes by 
, and all the sweet dishes by 
.
The possible different mix-and-match plates consisting of two savory dishes are as follows:
There are 9 plates with 
from sweet plates which are 
There are 9 plates with 
from sweet plates which are 
Similarly, there are 9 plated for each 
and 
Hence, the total number of the different mix-and-match plates consisting of two savory dishes
