Answer:
The inequality is 
Step-by-step explanation:
Total time:
The total time to complete the test is the sum of the number of multiple-choice questions multiplied by the time it takes to solve each and the number of short-answer questions multiply by the time it takes to solve each.
In this question:
Same number(n) of both.
Multiple-choice takes 2 minutes, short-answer takes 3.5 minutes. The total time is given by:

Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.?
This means that:

So

The inequality is 
I hope this helps you
t=r/r-3
t. (r-3)=r
t.r-3t=r
t.r-r=3t
r (t-1)=3t
r=3t/t-1
Theorem: If two chords intersect within a circle, then the product of the lengths of the segments (parts) of one chord is equal to the product of the lengths of the segments of the other chord.
In oyur case,

Solve this equation to find x:

Answer: 6, choice B.
Answer:
3, 5, 7
Step-by-step explanation:
As per triangle inequality theorem:
- <em>Any side of a triangle must be shorter than the other two sides added together</em>
Assume the sides are equal to 3 smallest odd numbers: 1,3 and 5
- Then 1+3< 5 and it is against the above rule, so this is not correct
The next triple is: 3, 5 and 7
- Then 3+ 5 > 7 and it is correct
So 3, 5, 7 is the combination of smallest odd numbers to make sides of a triangle
