Solve the equation. Check your answer.
k-9/2=11
k=
k = 23
To check the answer, substitute k = 23 into the equation:
23 - 9/2 = 23 - 4.5 = 18.5
The left side of the equation equals the right side, so the answer is correct.
no
Apologies for the mistake. Let's solve it again.
To solve the equation k - 9/2 = 11, we need to isolate the variable k.
First, let's simplify the equation by subtracting 9/2 from both sides:
k - 9/2 + 9/2 = 11 + 9/2
k - (9/2) + (9/2) = 11 + 9/2
k = 11 + 9/2
Next, let's find a common denominator for 11 and 9/2, which is 2:
k = 11(2/2) + 9/2
k = 22/2 + 9/2
k = (22 + 9)/2
k = 31/2
So, the solution to the equation is k = 31/2.
To check the answer, substitute k = 31/2 into the equation:
31/2 - 9/2 = 15.5 - 4.5 = 11
The left side of the equation equals the right side, so the solution is correct.
To solve the equation, we need to isolate the variable k.
Step 1: Distribute the 2 to the terms inside the parentheses on the left side of the equation.
k - (9/2) = 11
k - 9/2 = 11
Step 2: Add 9/2 to both sides of the equation to isolate the variable.
k - (9/2) + (9/2) = 11 + (9/2)
k = 11 + (9/2)
Step 3: Simplify the right side of the equation.
k = 11 + 4.5
k = 15.5
So, the solution to the equation is k = 15.5.
To check the answer, substitute k = 15.5 back into the original equation and see if both sides are equal.
(15.5) - 9/2 = 11
15.5 - 4.5 = 11
11 = 11
Since both sides are equal, the solution k = 15.5 is correct.
To solve the given equation, we need to isolate the variable "k" on one side of the equation.
Step 1: Distribute the fraction 9/2 to the term inside the parentheses.
k - (9/2) = 11
Step 2: Add (9/2) to both sides of the equation to move it to the right side.
k - (9/2) + (9/2) = 11 + (9/2)
Simplifying both sides:
k = 11 + (9/2)
Step 3: To combine 11 and (9/2), we need to have a common denominator, which in this case is 2.
k = (22/2) + (9/2)
Simplifying both sides:
k = (31/2)
So, the value of k that satisfies the equation is k = 31/2.
To check if this answer is correct, substitute the value of k back into the original equation:
(31/2) - 9/2 = 11
31/2 - 9/2 = 11
Simplifying both sides:
(31 - 9) / 2 = 11
22 / 2 = 11
11 = 11
The equation is true, which means our answer k = 31/2 is correct.
