Rectangle QRST, find x and y with QT=3x-10, RS=2y, and TS= 4y

x = 4, y = 1

Step-by-step explanation:

The opposite sides of a rectangle are congruent , thus

x = 4y → (1)

3x - 10 = 2y → (2)

Substitute x = 4y into (2)

3(4y) - 10 = 2y, that is

12y - 10 = 2y ( subtract 2y from both sides )

10y - 10 = 0 ( add 10 to both sides )

10y = 10 ( divide both sides by 10 )

y = 1

Substitute y = 1 into (1)

x = 4(1) = 4

Thus x = 4 and y = 1

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.
