Hey big men i need help with this question if you get it right you get brainliest. no bots also

 " $ 1.29 per roll " .

Step-by-step explanation:

Given:  C = (1.29) r ;

We are asked to find the cost of one rol,l;

in dollars per single roll.

Since "r" refers to "number of rolls" ;

Let "r" be equal to "1" ; and solve for "C" ;

  C = (1.29) r ;

     = (1.29)*(1) ;

     = (1.29) .

The answer is:  " $ 1.29 per roll " .

Hope this is helpful!

Best wishes!

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
