Answer:
308.2
Step-by-step explanation:
≈
≈ is approximately
(a^3-2a^2)-(3a^2-4a^3)
(a^3-2a^2)-3a^2+4a^3
5a^3-5a^2
60 is 25% of 240 and 12 is 24% of 50
25% is a fourth of 100%. So you want to find what number 60 is a fourth of. Multiply 60 by 4.
60x4=240
24% is 4.17th of 100%. Multiply 12 by 4.17
12x4.17=50
The way that it is written is odd.
If the problem was 3(x-5)=30, it would be 3x-15=30.
Add 15 to both sides.
3x=45
Divide both sides by 3.
x=15
If it's supposed to be 3(x-5)<30, your answer would be the same, except:
x<15.
I'm not sure why it has both signs, especially next to each other.
I hope this helps :)
