Answer 1

Answer:

-94.1

Step-by-step explanation:

(-5)(-3)0.5+(5)(4)(-5) - (4)(0.4)

Answer 2

The value of the expression = - 95.6

Given :

The expression bxy + 5ab - ay

To find :

The value of the expression for a = 4, b = - 5, c = 0.6 , x = - 3 , y = 0.4 , z = 0.5

Solution :

Step 1 of 2 :

Write down the given expression

Here the given expression is bxy + 5ab - ay

Step 2 of 2 :

Find the value of the expression

Expression = bxy + 5ab - ay

Putting a = 4, b = - 5 , x = - 3 , y = 0.4 in the expression we get ,

The value of the expression

= - 5 × (- 3) × 0.4 + 5 × 4 × (- 5) - 4 × 0.4

= 6 - 100 - 1.6
