Answer:
x=44
Step-by-step explanation:
For the two lines to be parallel, the two angles have to add to 180 degrees
45+3x+3 =180
Combine like terms
3x+48 = 180
Subtract 48 from each side
3x+48-48=180-48
3x=132
Divide each side by 3
3x/3 = 132/3
x =44
We are given
total number of DVDs=85
price of each DVDs=$19
we have to find total amount of money
total amount of money = (total number of DVDs)*(price of each DVDs)
total amount of money =85*19
total amount of money =$1615
now, we know that 1615 is more close to 1600 than 1700 because both are nearest hundredth
so,
total amount of money is $1600.........Answer
