Answer:
x>169/3
Step-by-step explanation:
x- the money that each earned
3x>197-28
3x>169
x>169/3
Well 13 /3 = 4.3333, that sure the cost for one book and the rate. so if he bought 12 books at the same rate, then its 12*4.33333. which equals 52 dollars
Angles 1, 2, and 3 are all 90°.
10x = 90
.. x = 9
x +y = 90
.. y = 81
5z = 90
.. z = 18
The values of (x, y, z) are (9, 81, 18).
