Evaluate the expression by using the given values of the variables. y ÷ 3 • 2 – 8 ÷ x + 5 where x = 4 and y = 12 A. 21 B. 9 C. 5 D. 11 @black_ninja123

Mehek (mehek14):

substitute 4 for x and 12 for y so you equation becomes: 12/3 * 2 - 8 /4 + 5

Mehek (mehek14):

now solve using PEMDAS

Mehek (mehek14):
