Question

X-0.2y-0.7x-10+0.5y-0.3x-18 при x=100.1 и y=-30

Answer 1

=0х+0,3у-28=0+0,3*(-30)-28=
-9-28=-37

Answer 2

To evaluate the given expression when x = 100.1 and y = -30, simply substitute the values of x and y into the expression and perform the calculations step by step:

Expression: X - 0.2y - 0.7x - 10 + 0.5y - 0.3x - 18

Step 1: Substitute the values of x and y: X - 0.2(-30) - 0.7(100.1) - 10 + 0.5(-30) - 0.3(100.1) - 18

Step 2: Perform the calculations: X + 6 - 70.07 - 10 - 15 - 30.03 - 18

Step 3: Combine like terms: X - 127.1

So, the value of the expression when x = 100.1 and y = -30 is X - 127.1. However, the value of 'X' itself is not given in the expression you provided. If you have the value of 'X,' you can substitute it into the expression to get the final result.
