Evaluate3x+2y-2z when x=5.5y=2and z =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.
To evaluate 3x + 2y - 2z when x = 5.5, y = 2, and z = 1, follow these steps:
Step 1: Substitute the given values of x, y, and z into the expression.
3(5.5) + 2(2) - 2(1)
Step 2: Simplify the expression.
16.5 + 4 - 2
Step 3: Perform the addition and subtraction.
20.5 - 2
Step 4: Calculate the final result.
18.5
Therefore, when x = 5.5, y = 2, and z = 1, the value of 3x + 2y - 2z is 18.5.
To evaluate the expression 3x + 2y - 2z when x = 5.5, y = 2, and z = 1, you simply substitute the given values into the expression and perform the calculations.
Step 1: Substitute the given values into the expression
3x + 2y - 2z = 3(5.5) + 2(2) - 2(1)
Step 2: Perform the calculations
3(5.5) = 16.5
2(2) = 4
2(1) = 2
Therefore,
3x + 2y - 2z = 16.5 + 4 - 2
= 20.5
Hence, when x = 5.5, y = 2, and z = 1, the value of 3x + 2y - 2z is equal to 20.5.
