The inequality that represents the number of right answers (r) and wrong answers (w) Olga can give to win the contest is:  3r-w>100

<u><em>Explanation</em></u>

Number of right answers is  r and number of wrong answers is  w

Olga earns 12 points for each right answer and loses 4 points for each wrong answer.

So, total points earned for r right answers =12r

and total points lost for w wrong answers =4w

That means, <u>her score will be</u>:  (12r-4w) points.

In order to win the quiz contest, Olga must score <u>more than 400 points</u>. So, the inequality will be.......

12r-4w>400\\ \\4(3r-w)>400\\ \\  3r-w>100

How many solutions does this equation have?
kozerog [31]

Hello from MrBillDoesMath!


Answer: infinite solutions


Discussion: I did a double take on this one but  the left hand is

a + 3 + 2a =  3a +3

and the right hand side is

-1 + 3a + 4 = 3a + (4-1) = 3a + 3


The left and right sides of the equation are identical for all "a", i.e. for infinitely many "a" values.


Regards, MrB.

In this item, we are tasked to determine the calculation that can be done in order to determine the length or width of the painted mural in each striped area. This can be done by dividing the total length by the number of stripes as shown in the equation below.

   Length per stripe = Total length / number of stripes
