I don't know how to make a 'greater than' sign.
6x is greater than x + 20
6x - x is greater than 20
5x is greater than 20
x is greater than 20 divided by 5
x is greater than 4
So, any number greater than 4 will work in this equation.
Answer:
x = 14
Step-by-step explanation:
3/7 = 6/x
3(x) = 6(7)
3x = 42
x = 14

Answer:
Step-by-step explanation:
x + 159 = 180
x = 21
= (7u³ + 8u² + 7) + (8u³ - 3u + 7)
Operate like terms together:
= 7u³ + 8u³ + 8u² - 3u + 7 + 7
= 15u³ + 8u² - 3u + 14
In short, Your Answer would be: 15u³ + 8u² - 3u + 14
Hope this helps!
