Evan and Peter have a radio show which consists of 2 segments. They need 4 less than 11 songs in the first segment. In the second segment, they need 5 less than 3 times the number of songs in the first segment. Part A Write an expression for the total number of songs they need for their show. A. ( 11 − 4 ) + 3 × 11 − 4 − 5 B. ( 11 − 4 ) + 3 × ( 11 − 4 ) − 5 C. ( 11 − 4 ) + 3 − 4 × 11 − 5 D. ( 11 − 4 ) + 3 − 5 × ( 11 − 4 )

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
