Answer:

B

Step-by-step explanation:

A. these simply to 21 + 7x and 21 + 3x

  • this one is incorrect because the 7x and 3x are different

B. these simplify to 10 + x and 10 + x

  • this is the correct one since they are exactly the same

C. these simplify to 21x and 7x + 21

  • these two are not the same because one expression has only a number with a variable but the other one has a number with a variable <em>and </em>another number

D. these simplify to  \frac{7}{3-x}  and  \frac{7}{x-3}

  • in subtraction, the order of the 3 and the x matters, so the equations are not the same
  • example: 6 - 4 = 2 but 4 - 6 = -2

Solve the absolute value equation:<br><br> |3x+3|=10
yarga [219]

Answer:

  • x = 2.33

Step-by-step explanation:

We know that when there is an absolute value sign, the value inside the bars is always positive.

  • => I3x + 3I = 10
  • => 3x + 3 = 10
  • => 3x = 10 - 3
  • => 3x = 7
  • => x = 7/3
  • => x = 2.33 (Rounded to nearest hundredth)

Hence, the value of x is 2.33.
