To solve the equation \( \frac{1}{3}(6x - 9) = -33 \), we can follow these steps logically:

Step 1: Multiply both sides of the equation by 3 to eliminate the fraction:

  • Response: Multiply by 3 on both sides of the equation.

Step 2: Simplify the left side and the right side: After multiplying, we have \( 6x - 9 = -99 \).

Step 3: Add 9 to both sides of the equation to isolate the term with \( x \):

  • Response: Add 9 to both sides of the equation.

So the correct order of the steps is:

Step 1: Multiply by 3 on both sides of the equation.
Step 2: Add 9 to both sides of the equation.
Step 3: Finally solve for \( x \) (not listed in the options but is the next implied step).

Note: The remaining operations to solve for \( x \) after step 3 involve dividing by 6. If necessary, that step could be included depending on the completeness required.

x = -19

Let's solve the equation \( \frac{1}{3}(6x - 9) = -33 \) step-by-step:

  1. Multiply both sides by 3 to eliminate the fraction: \[ 6x - 9 = -99 \]

  2. Add 9 to both sides to isolate the term with \( x \): \[ 6x = -99 + 9 \] \[ 6x = -90 \]

  3. Divide both sides by 6 to solve for \( x \): \[ x = \frac{-90}{6} = -15 \]

Thus, the solution for \( x \) is: \[ \boxed{x = -15} \]

So the correct response from your options is:

  • x = -15

Step 3:

:: Multiply both sides of the equation by -3/5
:: Divide both sides of the equation by -3/5
:: Divide both sides of the equation by 30.
::Subtract 30 from both sides of the equation.
Add 15 to both sides of the equation.
Divide both sides of the equation by 15.
:: Multiply both sides of the equation by 9.
Add 30 to both sides of the equation.

To solve the equation \( -\frac{3}{5}(15x - 30) = 198 \), we can follow these steps logically:

Step 1: Multiply both sides of the equation by \( -\frac{5}{3} \) to eliminate the fraction:

  • Response: Divide both sides of the equation by \( -\frac{3}{5} \).

Step 2: Simplifying the left side will give you \( 15x - 30 = -330 \) after multiplying.

Step 3: Add 30 to both sides of the equation to isolate the term with \( x \):

  • Response: Add 30 to both sides of the equation.

This gives you \( 15x = -300 \).

Lastly, you could then divide by 15 to solve for \( x \) (not included in the options).

So, the correct order of steps is:

Step 1: Divide both sides of the equation by \( -\frac{3}{5} \).
Step 2: Add 30 to both sides of the equation.
Step 3: (optional to finish) Divide both sides by 15 (which can be inferred as the next step to solve for \( x \)).

Note: If you prefer not to include inferred steps, only the first two would be necessary to satisfy the query.

Let's solve the equation \( -\frac{3}{5}(15x - 30) = 198 \) step-by-step.

  1. Multiply both sides by \( -\frac{5}{3} \) to eliminate the fraction: \[ 15x - 30 = 198 \cdot \left(-\frac{5}{3}\right) \] To simplify the right side: \[ 198 \cdot -\frac{5}{3} = -\frac{990}{3} = -330 \] Thus, we have: \[ 15x - 30 = -330 \]

  2. Add 30 to both sides: \[ 15x = -330 + 30 \] \[ 15x = -300 \]

  3. Divide both sides by 15: \[ x = \frac{-300}{15} = -20 \]

Therefore, the solution for \( x \) is: \[ \boxed{x = -20} \]

So from your options, the correct response is:

At Mariah's birthday party, 9 of her friends ate 3/4
of her chocolate cake. How much of the cake did each friend eat?(1 point)
Responses

6 3/4
6 and 3 fourths

1/9
1 ninth

1/12

To find out how much of the cake each friend ate, we first need to determine how much cake 9 friends ate together and then divide that amount by the number of friends.

  1. Total amount of cake eaten by the friends: \[ \frac{3}{4} \text{ of the cake} \]

  2. Number of friends: \[ 9 \text{ friends} \]

  3. Amount of cake eaten by each friend: We divide \(\frac{3}{4}\) by \(9\): \[ \text{Amount eaten by each friend} = \frac{3}{4} \div 9 = \frac{3}{4} \times \frac{1}{9} = \frac{3}{36} = \frac{1}{12} \]

Thus, each friend ate \(\frac{1}{12}\) of the cake.

Therefore, the correct response from your options is:

  • \( \frac{1}{12} \)

Step 4:

:: Distribute 1/4 to each term inside the parentheses.
Subtract 7 from both sides of the equation.
:: Add 4 to both sides of the equation.
:: Subtract 4 from both sides of the equation.
:: Divide by 1/4 on both sides of the equation.
:: Divide by 2 on both sides of the equation.
:: Combine like terms on the left side of the equation.
Subtract 7 from 12 on the left side of the equation.

Let's solve the equation \( \frac{1}{4}(8m + 12) - 7 = -2 \) step-by-step and choose the correct order of operations:

  1. Step 1: Add 7 to both sides to eliminate the -7: \[ \frac{1}{4}(8m + 12) = -2 + 7 \] This simplifies to: \[ \frac{1}{4}(8m + 12) = 5 \]

  2. Step 2: Multiply both sides by 4 to eliminate the fraction: \[ 8m + 12 = 20 \] (This step is equivalent to dividing by \( \frac{1}{4} \), but it’s easier to understand as multiplying by 4, so we can specify it clearly here.)

  3. Step 3: Subtract 12 from both sides to isolate the term with \( m \): \[ 8m = 20 - 12 \] This simplifies to: \[ 8m = 8 \]

  4. Step 4: Divide by 8 to solve for \( m \): \[ m = 1 \]

Given these steps, here is the organized order:

Step 1: Add 7 to both sides of the equation.
Step 2: Multiply by 4 on both sides of the equation (or divide by \( \frac{1}{4} \)).
Step 3: Subtract 12 from both sides of the equation.
Step 4: Divide by 8 on both sides of the equation.

So the correct selections in order are:

  1. Add 7 to both sides of the equation.
  2. Divide by 1/4 on both sides of the equation.
  3. Subtract 12 from both sides of the equation.
  4. Divide by 8 on both sides of the equation.

(Note: If "Divide by 8" is not present, use the statement "Combine like terms on the left side of the equation" instead, as this step concludes the simplification as well.)
