Answer:
<u>Option B</u>
Step-by-step explanation:
The question is as following:
![x+\frac{1}{2} (6x-4) =6](https://tex.z-dn.net/?f=x%2B%5Cfrac%7B1%7D%7B2%7D%20%286x-4%29%20%3D6)
Step Work Justification
1 2x + 6x − 4 = 12
2 8x − 4 = 12
3 8x = 16
4 x = 2
Which of the following has all of the correct justifications Wyatt used to solve this equation?
A. Distributive property. 2. Combine like terms. 3. Addition property of equality. 4. Division property of equality.
B. Multiplication property of equality. 2. Combine like terms. 3. Addition property of equality. 4. Division property of equality.
C. Distributive property. 2. Combine like terms. 3. Subtraction property of equality. 4. Division property of equality.
D. Multiplication property of equality. 2. Combine like terms. 3. Subtraction property of equality. 4. Division property of equality
<u />
<u>The answer:</u>
Step Work Justification
multiply both sides by 2
1) 2x + 6x − 4 = 12 ⇒ {Multiplication property of equality}
{Combine like terms}
2) 8x − 4 = 12 ⇒
Adding 4 both sides
3) 8x = 16 ⇒ {Addition property of equality}
divide both sides by 8
4) x = 2 ⇒ {Division property of equality}
The answer is option B
(B) Multiplication property of equality. 2. Combine like terms. 3. Addition property of equality. 4. Division property of equality.
Answer: Try to use socratic
Step-by-step explanation:
Answer:
The exterior angle of 60° is 120°. The exterior angle of 65° is 115°. The exterior angle of 55° is 125°.
Step-by-step explanation:
The sum of the interior angle and the exterior angle is 180°. So you can subtract each interior angle from 180 and get the exterior angle.
180° - 60° = 120°
180° - 65° = 115°
180° - 55° = 125°
This is because you can imagine the lines of the triangle extending beyond the triangle. Then you can see where the other angles are. Hope this makes sense!
So you do 3/4 divided by 6000 which make the thing switches and so you make 4/3 times by 6000 equals to your answers so you gotten 24,000 dividend it by 3 so you get will get.
Answer: 8,000
61.
40 ==> 100 %
x ==> 15 %
15*40/100 = 6.
Therefore, merely 6 students received C grades.
62.
23 500 ==> 100%
x ==> 42 %
42*23500/100 = 9870
Therefore 9870 people in the town are over 45 years of age.
You continue wth this method and you'll find for the 63, 64, 65.
In maths, you have to understand what you're doing dude ^^.
Whatever the answer for 64 and 65 are
64.
21.50*20/100 = 4.3
65.
250 ==> 100 %
45 ==> x %
x = 45*100/250 = 18 %
i will let you do the 63 alone, give me what you have found in the comments, i'll verify your answer.
Hope this helps !
