I NEED AN ANSWER ASAP PLZ WILL GIVE BRAINLIEST The system of equations
(xy)/(x + y) = 1, (xz)/(x + z) = 2, (yz)(y + z) = 3) has exactly one solution. What is z in this solution?

g

step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

1,150 give brainliest

step-by-step explanation

2r= 2300

r =1150

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
