One method for solving 3 (x - 4) = 18 is to first divide by 3, then add 4. Which method below would
also result in the correct answer?
One method that would also result in the correct answer for solving 3 (x - 4) = 18 is to first add 4 and then divide by 3.
Not an answer choice
Apologies for the confusion. Another method that would result in the correct answer for solving 3 (x - 4) = 18 is to first subtract 4 from both sides of the equation and then divide both sides by 3.
Wrong again fool
Apologies for the incorrect response. Another method that would result in the correct answer for solving 3 (x - 4) = 18 is to first distribute the 3 to the terms inside the parentheses, resulting in 3x - 12 = 18. Then, you can add 12 to both sides of the equation to isolate the variable term, giving you 3x = 30. Finally, divide both sides by 3 to solve for x, which gives you the correct answer x = 10.
Sorey i was on wrong question
No problem! If you were referring to a different question, please let me know and I'll be happy to help you with it.
When solving the equation - (x + 10) = -3, identify the operation that should be done first.
When solving the equation - (x + 10) = -3, the operation that should be done first is to remove the negative sign from the expression -(x + 10). This can be done by multiplying both sides of the equation by -1.
When solving the equation -1/2 (x + 10) = -3, identify the operation that should be done first.
When solving the equation -1/2 (x + 10) = -3, the operation that should be done first is to remove the coefficient -1/2 from the expression -1/2 (x + 10). This can be done by multiplying both sides of the equation by the reciprocal of -1/2, which is -2.
Three adult and three child movie tickets were purchased for $75. The cost of each child ticket is $3 less than the cost of an adult ticket. Identify the first step if solving this problem arithmetically, which would find the cost of one adult and one child ticket.
To find the cost of one adult and one child ticket, the first step would be to set up a system of equations based on the given information. Let's say the cost of an adult ticket is $x. Then, the cost of a child ticket would be $x - $3 (since the cost of each child ticket is $3 less than the cost of an adult ticket).
The system of equations would be:
3x + 3(x - $3) = $75
The first step in solving this problem arithmetically would be to distribute the 3 to the terms inside the parentheses:
3x + 3x - 9 = $75
Simplifying the equation further would lead to the next steps in solving the problem.
Three adult and three child movie tickets were purchased for $75. The cost of each child ticket is $3 less than the cost of an adult ticket. The first step to solving this problem algebraically is to write an
equation: 3 (x + x - 3) = 75, where x represents the cost of an adult ticket. Identify the next step,
which would simplify the equation before solving for the variable.
The next step would be to simplify the equation before solving for the variable x. In this case, we can start by simplifying the expression inside the parentheses:
3 (x + x - 3) = 75
Simplify the expression inside the parentheses:
3 (2x - 3) = 75
Now, we can distribute the 3 to the terms inside the parentheses:
6x - 9 = 75
The equation has been simplified, and the next step would be to isolate the variable x and solve for its value.
Three adult and three child movie tickets were purchased for $75. The cost of each child ticket is $3
less than the cost of an adult ticket. Find the price of each ticket.
Let's assume the cost of an adult ticket is "x" dollars.
According to the given information, the cost of each child ticket is $3 less than the cost of an adult ticket, so the cost of a child ticket would be (x - $3) dollars.
Now, let's set up an equation using the given information:
Three adult tickets plus three child tickets were purchased for a total of $75, so we can write:
3x + 3(x - $3) = $75
To simplify the equation, we need to distribute the 3 to the terms inside the parentheses:
3x + 3x - 9 = $75
Combining like terms, we have:
6x - 9 = $75
To isolate the variable x, we will add 9 to both sides of the equation:
6x = $84
Finally, to solve for x, we divide both sides of the equation by 6:
x = $14
Therefore, the cost of an adult ticket is $14, and the cost of a child ticket would be $14 - $3 = $11.
