Work: Solve for B R=x (A+B) distribute R=Ax+Bx -Ax both sides R-Ax=Bx ÷x both sides (R-Ax)/x=B Answer: B=(R-Ax)x or B= (R/x)-A Check your work: Plug in B R=x (A+(R-Ax)/x) R=x (A+R/x-A) R=x (R/x) R=R
Line up the numbers from least to greatest. 39, 42, 44, 51, 55, 62, 66, 72, 77, 81, 94, 86 Then find the Median. Look at the upper part of the data set and from there find the 3rd quartile.
