The answer to this is A) 12 ft
Answer:
Step-by-step explanation:
x + 2y = 14 ...............(1)
6x + 3y = 21 ..............(2)
Solve for x in equation 1
When x + 2y = 14
Therefore x = 14 - 2y ...................(3)
Now put equation 3 in equation 2 and solve
6x + 3y = 21 .............(2)
6(14 - 2y) + 3y = 21
Open the bracket and resolve
84 - 12y + 3y = 21
-9y + 84 =21
Now collect the like terms
-9y + 84 = 21
-9y = 21 - 84
-9y = -63
Divide through by -9 to get y
y = -63/-9
y = 7
Substitute for y in equation( 3 )to x
x= 14 - 2y............(3)
So, x = 14 - 2(7)
x = 14 - 14
x = 0.
Therefore x = 0 and y = 7
Check: From equation (1)
x + 2y = 14
Now, put x = 0 and y = -2
Therefore, 0 +2(7) =14
0 +14 = 14
Since this limit exceeds 1, the series diverges.
Answer:
4 whole number, 7/24
Step-by-step explanation:
Thats correct i didnt had any explination because i wrote it on a paper
Answer:
Mean: Use any 5 numbers that make 25.
Median: 5
Step-by-step explanation:
For the mean you can use 2.5+2.5+2.5+7.5+10
I'm not sure about the median... If it's asking about the median for the set I used, it would be 2.5. If it's asking about the one gives, not including the zero would be 5.
