w/8+2=11, and then creating equation from a table

1 answer

To solve the equation \( \frac{w}{8} + 2 = 11 \), you can follow these steps:

  1. Isolate the Fraction: Subtract 2 from both sides of the equation: \[ \frac{w}{8} + 2 - 2 = 11 - 2 \] This simplifies to: \[ \frac{w}{8} = 9 \]

  2. Eliminate the Fraction: To eliminate the fraction, multiply both sides by 8: \[ 8 \times \frac{w}{8} = 9 \times 8 \] This simplifies to: \[ w = 72 \]

So, the solution to the equation \( \frac{w}{8} + 2 = 11 \) is \( w = 72 \).

Creating an Equation from a Table

If you have a table of values, you can create an equation that describes the relationship between the input (often \( x \)) and output (often \( y \)). For example, consider the following table of values:

| \( x \) | \( y \) | |---------|---------| | 0 | 2 | | 1 | 3 | | 2 | 4 | | 3 | 5 | | 4 | 6 |

Steps to Create an Equation:

  1. Identify the Pattern: In this table, as \( x \) increases by 1, \( y \) increases by 1 as well.

  2. Write the Equation: From the observed pattern, we can infer that the relationship is linear. The \( y \)-intercept (the \( y \) value when \( x = 0 \)) is 2. The slope (the rate of change) is 1 (since \( y \) increases by 1 for each increase of 1 in \( x \)).

    Therefore, the equation can be expressed as: \[ y = x + 2 \]

You would simply follow this approach of observing changes in \( x \) and \( y \) to create an equation based on your specific table of values. If you have a specific table you'd like help with, please provide it, and I can assist you further!
