Answer:
15x+13y> 3,000
Step-by-step explanation:
Answer:
Distributive property
Step-by-step explanation:
Solution:
Duration of time for which a contestant have to speak = 5 minutes (300 Seconds)
Point lost by a contestant for over-speaking that is for more than 5 minutes for each second = 3 points
Point lost by a contestant for speaking less than 5 minutes on each second = 3 points
So, the expression which can determine ,the number of points a contestant loses if she speaks for x seconds.
⇒Number of points a contestant loses if she speaks for x seconds=
For, example if a contestant speaks for 290 seconds,Points lost by contestant =
=3 × 10= 30 Points
If a contestant speaks for 305 seconds,Points lost by contestant =
=3 × 5= 15 Points
Option (A)=
is right choice describing above situation.
Multiplying both sides of a rational equation by a variable expression introduces the possibility of extraneous solutions. Therefore, we must check the solutions against the set of restrictions. If a solution is a restriction, then it is not part of the domain and is extraneous.
Answer:
a. IQR = 2.25
b. 40%
(I'm not sure about B.)
Step-by-step explanation:
a.=Q3 - Q1
=4.7 - 2.2
=2.5
b. =2/5 × 100/1
=40%
