Step-by-step explanation:
(3x + 5y - 7r)/(z + t) = 9p
3x + 5y - 7r = 9p(z + t)
3x + 5y - 7r = 9pz + 9pt
3x = 9pz + 9pt - 5y + 7r
x = (9pz + 9pt -5y + 7r)/3
The answer would be 56.
8/3x5
40,320/6x120
40,320/720
56
Hope this helped!
Answer:
117
Step-by-step explanation:
Sum of all angles of pentagon = 540
x + 86 + 140 + 138 + 59 = 540
x + 423 = 540
x = 540 - 423
x = 117
