Let \( x \) be the height of Karen's older sister in inches. According to the problem, we have the equation:

\[ 59 = \frac{x}{2} + 27 \]

To solve for \( x \), we first subtract 27 from both sides:

\[ 59 - 27 = \frac{x}{2} \]

\[ 32 = \frac{x}{2} \]

Next, we multiply both sides by 2 to solve for \( x \):

\[ x = 32 \times 2 \]

\[ x = 64 \]

Thus, Karen's older sister is 64 inches tall.

Susan read 17 pages today. That is 8 pages fewer than 1/3
of the pages she read yesterday. How many pages did she read yesterday?(1 point)
pages

Let \( x \) be the number of pages Susan read yesterday. According to the problem, we can create the equation:

\[ 17 = \frac{x}{3} - 8 \]

To solve for \( x \), we first add 8 to both sides:

\[ 17 + 8 = \frac{x}{3} \]

\[ 25 = \frac{x}{3} \]

Next, we multiply both sides by 3 to isolate \( x \):

\[ x = 25 \times 3 \]

\[ x = 75 \]

Therefore, Susan read 75 pages yesterday.

Anthony got a job babysitting. Each hour he works he will be paid $8.00. As a bonus, he will earn an additional $1.50 per hour for each child he watches. If his total hourly rate is $12.50, how many children does he watch?

To solve this problem, let's define \( x \) as the number of children Anthony watches.

Anthony's pay consists of two components:

  1. A base pay of $8.00 per hour.
  2. A bonus of $1.50 for each child he watches.

This means that his total hourly earnings can be represented as:

\[ 8 + 1.50x \]

We know from the problem that his total hourly rate is $12.50. Thus, we can set up the equation:

\[ 8 + 1.50x = 12.50 \]

In the form \( px + q = r \), we can identify:

  • \( p = 1.50 \)
  • \( q = 8 \)
  • \( r = 12.50 \)

So, the final equation is:

\[ 1.50x + 8 = 12.50 \]

Let \( x \) be the height of Cassandra’s younger brother in inches.

According to the problem, Cassandra's height (63 inches) is 6 inches less than 3 times her younger brother's height. We can express this relationship with the following equation:

\[ 63 = 3x - 6 \]

To convert this equation into the form \( px + q = r \), we want to rearrange it:

First, add 6 to both sides:

\[ 63 + 6 = 3x \]

\[ 69 = 3x \]

We can now express it in the desired form:

\[ 3x + 0 = 69 \]

Here, we can identify:

  • \( p = 3 \)
  • \( q = 0 \)
  • \( r = 69 \)

Thus, the final equation is:

\[ 3x + 0 = 69 \]

Since it simplifies further, you may also write:

\[ 3x = 69 \]

This equation is of the required form, and indicates the same relationship.

Check answer

Let's define \( x \) as the height of Cassandra’s younger brother in inches. According to the problem, Cassandra's height (63 inches) is described as 6 inches less than 3 times her younger brother's height. This leads to the following equation:

\[ 63 = 3x - 6 \]

To write it in the form \( px + q = r \), we need to rearrange the equation.

Adding 6 to both sides gives:

\[ 63 + 6 = 3x \]

\[ 69 = 3x \]

Now we put this in the form \( px + q = r \):

\[ 3x + 0 = 69 \]

From your prompt, it looks like you want to express it more clearly with placeholders. So we can format it as:

\[ 3x + 0 = 69 \]

where:

  • \( p = 3 \)
  • \( q = 0 \)
  • \( r = 69 \)

If we put this in the format you specified, it can be written as:

3x + 0 = 69

If you had a different structure in mind, please clarify! But based on what you've written, this should work.

Now, to solve for \( x \), we have:

\[ x = \frac{69}{3} = 23 \]

So, Cassandra’s younger brother is 23 inches tall.

wrong give me the right answer

I apologize for any confusion. Let's go through the problem step by step again.

Cassandra's height is given as 63 inches, and it is stated that this is 6 inches less than 3 times her younger brother's height. We can define \( x \) as the height of her younger brother.

The relationship can be expressed mathematically as:

\[ 63 = 3x - 6 \]

To rearrange this into the form \( px + q = r \), we can follow these steps:

  1. Add 6 to both sides: \[ 63 + 6 = 3x \] This simplifies to: \[ 69 = 3x \]

  2. Rearranging this gives us: \[ 3x + 0 = 69 \]

So in the desired form \( px + q = r \):

  • \( p = 3 \)
  • \( q = 0 \)
  • \( r = 69 \)

Now, to find \( x \):

  1. Divide both sides by 3: \[ x = \frac{69}{3} \] \[ x = 23 \]

So Cassandra's younger brother is 23 inches tall.

Thank you for your patience, and I apologize for any misunderstanding in the previous responses!
