Пошаговое объяснение:

=7*2 1/2-11=7*2.5-11=17.5-11=6.5

Answer 3

To evaluate the expression 7x - 11 at x = 2.1/2, first, let's simplify the value of x:

x = 2.1/2 = 2.1 ÷ 2 = 1.05

Now, substitute the value of x into the expression:

7x - 11 = 7 * 1.05 - 11

Now, calculate the result:

7 * 1.05 = 7.35

7x - 11 = 7.35 - 11 = -3.65

So, when x = 2.1/2, the value of the expression 7x - 11 is -3.65.
