Example Question - equation evaluation
Here are examples of questions we've helped users solve.
Variable Equations Evaluation
To solve this question, we need to plug in the given value for the variable into each equation and determine if the equation holds true. A. n + 7 = 16; n = 15 Substitute n = 15 into the equation: 15 + 7 = 22 This is not equal to 16, so the answer is No. B. 2/3v = 8; v = 12 Substitute v = 12 into the equation: 2/3 * 12 = 8 8 = 8 This is true, so the answer is Yes. C. 6z = 84; z = 8 Substitute z = 8 into the equation: 6 * 8 = 48 This is not equal to 84, so the answer is No. So the answers are: A. No B. Yes C. No
Equivalence of Equations Evaluation
The image shows a question that asks to select all of the equations that are equivalent to the equation "19d -2". Four different equations are listed as options. The equivalency check here would involve the use of properties of equality to ensure the expressions remain equivalent if the same operations are applied to both sides of these equations. Let me evaluate each option. For the first equation: 18 + 19d = 54 To check if it is equivalent to the original equation, we should isolate 19d on one side. Subtracting 18 from both sides gives us: 19d = 54 - 18 19d = 36 This is not equal to 19d - 2, so this equation is not equivalent to the original equation. For the second equation: 19d + 22 = 66 Subtracting 22 from both sides to isolate 19d: 19d = 66 - 22 19d = 44 Again, this is not equal to 19d - 2, so this equation is not equivalent to the original equation. For the third equation: 19d + 19 = 76 Subtracting 19 from both sides: 19d = 76 - 19 19d = 57 This is not equal to 19d - 2, so this equation is not equivalent to the original equation either. For the fourth equation: 19d + 6 = 12 Subtracting 6 from both sides: 19d = 12 - 6 19d = 6 This is not equal to 19d - 2, so this equation is also not equivalent to the original equation. None of the provided options is equivalent to "19d - 2".
