Start with Original Equation: To determine if an equation is equivalent to qr = 13, we can manipulate the original equation and compare it to the choices given. We start with the original equation: qr = 13Compare with Choice (A): Now let's compare the original equation to choice (A): qr - 4 = 10 To check if this is equivalent, we can add 4 to both sides of the equation qr = 13: qr + 4 = 13 + 4 qr + 4 = 17 This is not equal to 10, so choice (A) is not equivalent to qr = 13.Compare with Choice (B): Next, we compare the original equation to choice (B): qr - 4 = 9 Again, we add 4 to both sides of the equation qr = 13: qr + 4 = 13 + 4 qr + 4 = 17 This is not equal to 9, so choice (B) is not equivalent to qr = 13.Compare with Choice (C): Now we compare the original equation to choice (C): qr - 2 = 13 To check if this is equivalent, we can add 2 to both sides of the equation qr = 13: qr + 2 = 13 + 2 qr + 2 = 15 This is not equal to 13, so choice (C) is not equivalent to qr = 13.Compare with Choice (D): Finally, we compare the original equation to choice (D): qr - 3 = 9 To check if this is equivalent, we can add 3 to both sides of the equation qr = 13: qr + 3 = 13 + 3 qr + 3 = 16 This is not equal to 9, so choice (D) is not equivalent to qr = 13.
