Lindsey made an error while solving the equation 143.5 = 2 - 7(x + 3). What line has the error?

A.143.5=2-7(x+3)

B.143.5=2+7x-21(step 1)

C.143.5=7x-19(step 2)

D.162.5=7x(step3)

E.23.214=x(step 4)

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.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

5/12, or 5: 12
