Question

4,8b-3,4b+2,6b-1,8,якщо b=0,8​

Answer 1

Ответ:1.4

Пошаговое объяснение:

b(4.8-3.4+2.6)-1.8

0.8•4-1.8=1.4

Answer 2

4,8*0,8-3,4*0,8+2,6*0,8-1,8=1,4

Answer 3

To evaluate the expression 4b - 3.4b + 2.6b - 1.8 when b = 0.8, you simply need to substitute the value of b into the expression and perform the calculations.

Replace b with 0.8 in the expression:

4(0.8) - 3.4(0.8) + 2.6(0.8) - 1.8

Now, calculate each term:

4(0.8) = 3.2 3.4(0.8) = 2.72 2.6(0.8) = 2.08

Now, substitute the calculated values back into the expression:

3.2 - 2.72 + 2.08 - 1.8

Finally, perform the arithmetic operations:

(3.2 - 2.72) + 2.08 - 1.8 = 0.48

So, the value of the expression when b = 0.8 is 0.48.
