The value of d which will.make this system have the same solution is; d = 21/(3x -1)
First, we must make y, the subject of the formula in each case as follows;
- y = (3x -1)/7. and
- y = 3/d.
In essence, by equating y to y in both equations; we have;
By Cross-product; we have;

Answer: 2.71
Step-by-step explanation:
We know that the formula to calculate the standard error is given by :-
, where 
is the standard deviation and 'n' is the sample size.
Given : Standard deviation : 
Sample size : 
Then , the standard error of the mean is given by :-
Hence, the standard error of the mean = 2.71

6peaches=?
55*6=330grams
1kg=1000grammes
=330grams
330 divide 1000=0.33
1kg=5.50
0.33kg= Hence,0.33*5.50=1.815
