Question

-0,6(1,6b-5)-(2,9b-8)-4(4-1,5b) если b=-9/13 СРОЧНО​

Answer 1

Ответ:

Пошаговое объяснение:

= -0,96b + 3 - 2,9b + 8 - 16 + 6b =

2,14b - 5

b = -9/13

2,14b - 5 = 2,14 * (-9/13) - 5 =

2. 14/1 00 * (-9/13) - 5 =

2. 7/50 * (-9/13) - 5 =

107/50 * (-9/13) - 5 =

-963/650 - 5 = -1. 313/650 - 5 =

-6. 313/650

Answer 2

Ответ:

-6 313/650

Пошаговое объяснение:

= -0,96b+3-2,9b+8-16+6b=2,14b-5

b=-9/13

2,14×(-9/13)-5=2 14/100×(-9/13)-5=107/50×(-9/13)-5=

=963/650-5=-1 313/650-5=-6 313/650

Answer 3

I can help you with your math problem. To solve it, you need to substitute b with -9/13 and simplify the expression. Here are the steps:

-0.6(1.6b-5)-(2.9b-8)-4(4-1.5b) = -0.6(1.6(-9/13)-5)-(2.9(-9/13)-8)-4(4-1.5(-9/13))
= -0.6(-14.4/13-5)+25.2/13-8+16+54/13
= 8.64/13+3+25.2/13-8-16-54/13
= -21-54/13
= -321/13

The final answer is $$-321/13$$. I hope this helps.Ответь+подробно.++-0,6(1,6b-5)-(2,9b-8)-4(4-1,5b)+если+b=-9/13+СРОЧНО​+
