A class voted for either rollerblading, swimming, or biking as their favorite summer activity. If swimming got 43% percent of the vote and biking got 15%,
what percentage of the class voted for rollerblading?

Step-by-step explanation:

Percentage for Rollerblading

= Total - Percentage for Swimming - Percentage for Biking

= 100% - 43% - 15%

= 42%.

over the argument its not good to fight.

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
