A+(-1.6)=-3.7
+1.6 +1.6
a=-2.1
We have 2 angles that are supplementary, so their sum equals 180⁰.
(4x - 10) + (7x - 8) =180
11x - 18 = 180
11x = 198
x = 18
Answer:
number of tape sides = 2.1667 tape sides
Explanation:
We know that each song took 1/6 of a side of tape to be recorded.
To know how many tape sides were used to record 13 songs, all we have to do is cross multiplication as follows:
1 song ..................> 1/6 of a tape side
13 songs ..............> ?? tape sides
Number of tape sides = [(13) * (1/6)] / 1
number of tape sides = 2.1667 tape sides
Hope this helps :)
