What value of b will make the expressions −12.8x+b and −3.2(4x−2.1)+2.4 equivalent?

Sagot :

Answer:

  • b = 9.12

Step-by-step explanation:

Simplify the second expression and compare with the first one:

  • - 3.2(4x - 2.1) + 2.4 =
  • - 12.8x + 3.2*2.1 + 2.4 =
  • - 12.8x + 6.72 + 2.4 =
  • - 12.8x + 9.12

Comparing with the first expression the value of b is:

  • b = 9.12
