Use inductive reasoning to predict the next line in this sequence of computations. Then
AysviL [449]

The computation show that the next number based on the information will be 588886.

<h3>How to compute the value?</h3>

From the information given, the numbers are illustrated as:

2x9-2=16

32x9-2=286

432x9-2=3886

5432x9-2=4888

It should be noted that the next number will be:

(65432 × 9) - 2

= 588888 - 2

= 588886

Therefore, it can be seen that the next number based on the information is 588886.

Hey there! :)

Answer:

x = -7/12.

Step-by-step explanation:

Given:

x + \frac{5}{12} = -\frac{1}{6}

Create a common denominator for each term:

\frac{12x}{12} + \frac{5}{12} = -\frac{2}{12}

Disregard the denominator:

12x + 5 = -2

Subtract 5 from both sides:

12x = -7

Divide both sides by 12:

x = -7/12.
