Sam has $40. He buys a book for $12.99 and a puzzle for $15.49. Which equations can be used to find how much money Sam has left?
Select all that apply.
A. $40 – $28.48 = $11.52
B. $40 + $12.99 = $52.99
C.$15.49 – $12.99 = $2.50
D. $12.99 + $15.49 = $28.48
E. $40 – $2.50 = $37.50

40 describe the outliers from the scatter plot.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14

For the right triangle shown, the lengths of two sides are given. find the third side. leave your answer in simplified, radical form.
