If the range is 1, we can assume that every student in that history class studies for a very similar amount of time studying, within 1 minute to be specific.
Macro needs 90 megabytes of storage to store the whole video.
Step-by-step explanation:
Video downloaded = 80%
Data storage used = 72 MB
Let, x be the total data storage required for storing the whole video.
Therefore,
80% of x = 72
Dividing both sides by 0.8
Macro needs 90 megabytes of storage to store the whole video.

<u>Option B</u>
Step-by-step explanation:
The question is as following:
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>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.
