Dylan opened a credit card account with $700.00 of available credit. now that he has made some purchases, dylan's account only has $511.00 of available credit. what is the percentage decrease of the amount of available credit in dylan's account?

the 100% correct answer is- 34%

Step-by-step explanation: First, find the difference between the two amounts of credit available. ($550.00 - $363.00 = $187.00)

Then, divide by the original amount of credit available, and convert to a percent.  

The percentage decrease of the amount of available credit is 34%.

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

answer:

a=9
