Answer:
X = 18
Step-by-step explanation:
Question: The sum of three numbers in order is 57. the equation that represents this is x (x 1) (x 2) = 57. which value of x from the set {16, 17, 18, 19} makes the equation true?
Answer: First you can use the equation to work out the value of x.
x + (x + 1) + (x + 2) = 57
Simplify the equation.
3x + 3 = 57.
Now solve the equation.
57 - 3 = 54
54/3 = 18
In short, The value of x is 18.
