Answer 1

To evaluate the expression \( x - \frac{y}{3} \) for \( x = 9 \) and \( y = 6 \), follow these steps:

1. Substitute the values of \( x \) and \( y \) into the expression:

   \[ 9 - \frac{6}{3} \]

2. Calculate \( \frac{6}{3} \):

   \[ \frac{6}{3} = 2 \]

3. Now substitute this back into the expression:

   \[ 9 - 2 \]

4. Finally, perform the subtraction:

   \[ 9 - 2 = 7 \]

Therefore, the value of the expression \( x - \frac{y}{3} \) when \( x = 9 \) and \( y = 6 \) is \( 7 \).

However, none of the provided responses (6, 9, 1, 3) contain the correct answer of 7. Please check your options again!

Answer 3

To find out how much you will have saved after 4 weeks using the expression \( 45 + 3w \), where \( w \) represents the number of weeks, follow these steps:

1. Substitute \( w = 4 \) into the expression:

   \[ 45 + 3(4) \]

2. Calculate \( 3(4) \):

   \[ 3(4) = 12 \]

3. Now substitute this back into the expression:

   \[ 45 + 12 \]

4. Finally, perform the addition:

   \[ 45 + 12 = 57 \]

So, after 4 weeks, you will have saved $57.

The correct response from the options provided is $57.
