The general expression is 130 x - 600 and total points scored by the player is 1220
A) Let the number of correctly answered questions be x.
∴ Number of incorrectly answered questions will be 20 - x.
+ 100 points is awarded for each question answered correctly while -30 points is awarded for each question answered incorrectly.
Thus, the general equation becomes
= 100x - (20 - x)(-30)
= 100x +30x - 600
= 130x - 600
Thus the general expression becomes 130 x - 600
B) The player answers 14 questions correctly, thus x = 14
Substituting the value of x =14 in the general equation we get,
= 130(14) - 600
= 1820 - 600
= 1220.
Thus the total points scored by the player will be 1220

Answer:
3 minutes per table
Step-by-step explanation:
15 minutes = 5 tables
to get how much it will be per table, divided both sides by 5
since 5 / x = 1 and x would be 5
15 / 5 minutes = 5 / 5 tables
3 minutes = 1 table
Answer:
I need some more context
Step-by-step explanation:
Answer:
The correct option is c.
Step-by-step explanation:
The quotient of the polynomials is
We need to find the remainder by using long division method.
The dividend of the given expression is
The long division method is shown below.
From the below attachment it is clear that the quotient has a remainder of 30. Therefore, the divisor is not factor of the dividend.
Therefore the correct option is c.
