Answer 2

Объяснение:

3*a-4*b ,при a= 1,2; b=0,2

3*1,2 - 4 * 0,2 = 2,8

1)3*1,2 = 3,6

2)4*0,2 = 0,8

3)3,6 - 0,8 = 2,8

Answer 3

To find the value of the expression 3a - 4b when a = 1.2 and b = 0.2, simply substitute the values of a and b into the expression and perform the arithmetic:

3 * a - 4 * b

Replacing a with 1.2 and b with 0.2:

3 * 1.2 - 4 * 0.2

Now, perform the multiplication and subtraction:

3.6 - 0.8

Finally, calculate the result:

3.6 - 0.8 = 2.8

So, when a = 1.2 and b = 0.2, the value of the expression 3a - 4b is 2.8.
