i think this is correct?
121.38 should be the right answer
Answer:
Step-by-step explanation:
2x + 3 + 4x + 2 + 2x - 1 = 180 (bc the sum of the angles of a triangle = 180)
8x = 176
x = 22
2x + 3 = 47
4x + 2 = 90
2x - 1 = 43
If a number is positive, Leila's theory that 75% of a number will always be greater than 50% of another number is <em>true</em>;<em> </em>however, if both numbers are negative, or if the number of which she finds 50% is much greater than the number of which she finds 75%, Leila's theory could be incorrect.
This inequality shows that Leila is correct:
![100(0.75) \geq 50(0.50)](https://tex.z-dn.net/?f=100%280.75%29%20%5Cgeq%2050%280.50%29)
(which simplifies to
![75 \geq 25](https://tex.z-dn.net/?f=75%20%5Cgeq%2025)
)
This inequality shows that Leila is incorrect:
![50(0.75) \geq 100(0.50)](https://tex.z-dn.net/?f=50%280.75%29%20%5Cgeq%20100%280.50%29)
(which simplifies to
![37.5 \geq 50](https://tex.z-dn.net/?f=37.5%20%5Cgeq%2050)
)
Hope this helps!
