1 answer:
The question is incomplete. Here is the complete question:
Which inequality is true for x = 20?
A. x + 30 < 3x
B. x - 5 < 2x - 35
C. x divided by 4 < x - 12
D. 2x < x + 22
Answer:
Options A, B and D.
Step-by-step explanation:
Given:
The value of 'x' is 20.
In order to find which options are correct, we need to plug in 20 for 'x' in each of the given inequalities and check which of them hold true.
Option A:
Substitute 20 for 'x' in the above inequality. This gives,
The given inequality is true as 50 is less than 60.
Option B:
Substitute 20 for 'x' in the above inequality. This gives,
15 < 5
The given inequality is false as 5 is less than 15.
Option C:
Substitute 20 for 'x' in the above inequality. This gives,
5 < 8
The given inequality is true as 5 is less than 8.
Option D:
Substitute 20 for 'x' in the above inequality. This gives,
40 < 42
The given inequality is true as 40 is less than 42.
Therefore, the correct options are A, B and D.

Answer:
(3,6)
Step-by-step explanation:
Given that Mila reads at a rate of 2 paragraphs per minute. After reading for 3 minutes, she had read a total of 6 paragraphs.
This situation can be represented with a linear equation written in slope-intercept form, as
where 'x' represents the number of minutes and,
y represents the number of paragraphs.
Since y intercept is 0 i.e. 0 paras in 0 minutes we have the equation as
Since no of minutes or paragraphs cannot take negative values this line is defined only in the I quadrant where both x and y are positive
Out of the points given as follows:
(3,6) (2,3) (-3,6) or (-2,6) ,
we can remove last two since they have negative x which is impossible.
Consider (3,6) (2,3)
Out of these only I point (3,6) satisfies and second point (2,3) does not satisfy
Hence answer is (3,6)
