The work of a student to solve the equation 2(3x − 4) = 8 + 2x + 4 is shown below:
2 answers:
The correct answer is "<span>Step 2; 6x − 8 = 12 + 2x." </span> The step that the student first make an error is at the 2nd step. The correct step should be 6x − 8 = 12 + 2x. Finishing the steps: <span>Step 1: 2(3x − 4) = 8 + 2x + 4 </span>Step 2: <span>6x − 8 = 12 + 2x. Step 3: 4x = 20 Step 4: x = 5</span>
Answer:
Step 2; 6x − 8 = 12 + 2x
Step-by-step explanation:
Step 1: Write the equation
Step 2: Apply distributive property to the left side and sum the constants to the right side
Step 3: Subtract 2x from both sides and add 8 to both sides:
Step 4: Divide both sides by 4:

You can solve by subtracting: 500-330 but I like to use mental math and think this way: she has 330 70 more will give her 400 and 100 more will give her 500 100 + 70 is 170.
Answer:
x = (5,0)
Step-by-step explanation:
To find the x-intercept, substitute y with 0 and solve for x .
x + 2(0) = 5
Then, simplify.
Multiply 2 by 0 .
x + 0 = 5
Add x and 0 .
x = 5
So, the result will be x = (5,0)
Answer:
T hey Have The Same Y - Intercept .
Function 2's y-intercept is -5.
Function 1 y-intercept could be found by inputting 0 as r.
p=0-5
p=-5
Meaning, they're equal.
7 / 12 = 0.583333333 Divide them all to see which one equals 0.583333333. A. 8 / 13 = 0.615384615 B. 10 / 15 = 0.666666667 C. 14 / 19 = 0.736842105 D. 21 / 36 = 0.583333333 Therefore, your answer is D.
Answer:
as the triangles are similar their corresponding sides ( the sides opposite to the angles) are proportional to eachother
