Final answer:

The value of the expression (w2x−3)÷10⋅z when w = -6, x = 1.2, and z = -6/7 is approximately -3.4486.

Step-by-step explanation:

To evaluate the expression (w2x−3)÷10⋅z when w = -6, x = 1.2, and z = -6/7, we substitute the given values into the expression:

= ((-6)²(1.2) - 3) ÷ 10 * (-6/7)

= ((36)(1.2) - 3) ÷ 10 * (-6/7)

= (43.2 - 3) ÷ 10 * (-6/7)

= 40.2 ÷ 10 * (-6/7)

= 4.02 * (-6/7)

= -3.4486

Therefore, the value of the expression is approximately -3.4486.
