Q. Evaluate the expression for v=−0.4 and w=−9.3.Write your answer as a decimal or whole number.v−w=_____
Identify expression: Identify the expression to be evaluated.We are given the expression v−w and the values v=−0.4 and w=−9.3. We need to substitute these values into the expression.
Substitute values: Substitute the given values into the expression.Replace v with –0.4 and w with –9.3 in the expression v−w.Expression: (–0.4)−(–9.3)
Simplify expression: Simplify the expression.Subtracting a negative is the same as adding the positive equivalent of that number.(–0.4)−(–9.3)=(–0.4)+9.3
Perform addition: Perform the addition.Now, add –0.4 to 9.3.–0.4+9.3=8.9
