Answer:

I dont know the answer but I found out how you figure out if lines are supplementary

Step-by-step explanation:

1) let the measure of one of the supplementary angles be a

2) measure of the other angle is 2 times a

3) so the measure of the angle is 2a

4) if the sum of the two angles is 180 degrees then the angles are supplementary

you bought 5 chocolate bars and 8 blow pops for $23.25 your sister bought 2 chocolate bars and 13 blow pops for 21.55 how much d

kirza4 [7]

Answer:

$2.65

Step-by-step explanation:

Let chocolate bar = c and blow pops = b

As per given we have equations below:

5c + 8b = 23.25
2c + 13b = 21.55

13 times the first equation minus 8 times the second to eliminate b and find c:

13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)
65c - 16c = 129.85
49c = 129.85
c = 129.85/49
c = 2.65

Each chocolate bar costs $2.65
