Question

1 6/5x - 2/3x + 0,25x при х = 6 6,12у + 1 2/5у - 0,32у при у = 5

Answer 1

15÷5×6-2÷3×6+0,25×6=164
6,12×5+12÷5×5-0,32×5=2,912

Answer 2

To evaluate the given expressions, simply substitute the given values of x and y and perform the calculations.

1. For x = 6: 1 6/5x - 2/3x + 0.25x

Substitute x = 6: 1 6/5 * 6 - 2/3 * 6 + 0.25 * 6

Now perform the operations: = (6 + 2 - 1.5) + 1.5 = 7.5

So, when x = 6, the expression 1 6/5x - 2/3x + 0.25x equals 7.5.

2. For y = 5: 6.12y + 1 2/5y - 0.32y

Substitute y = 5: 6.12 * 5 + 1 2/5 * 5 - 0.32 * 5

Now perform the operations: = 30.6 + (5 + 2) - 1.6 = 37

So, when y = 5, the expression 6.12y + 1 2/5y - 0.32y equals 37.
