Evaluate3x+2y-2z when x=5.5y=2and z =1

Answer 1

To evaluate the expression 3x + 2y - 2z when x = 5.5, y = 2, and z = 1, we simply substitute the given values into the expression:

3x + 2y - 2z = 3(5.5) + 2(2) - 2(1)

Simplifying this, we get:

= 16.5 + 4 - 2

= 18.5

Therefore, when x = 5.5, y = 2, and z = 1, the value of 3x + 2y - 2z is 18.5.
