Answer:
10. 2x+y
11. x^2-15x+3
Step-by-step explanation:
10. when u add 7x+3y and 4x+4y you will get 11x+7y. 13x+8y minus 11x+7y will be 2x+y
11. when u add 3x^2+7x+1 and x^2-x+1 u will get 4x^2+6x+2. 5x^2-9x+5 minus 4x^2+6x+2 will be x^2-15x+3
Answer:
Third Option
Step-by-step explanation:
3x + 18 > 6x - 9
We have to find the value of x for this
Subtract 18 from both sides to leave 3x alone
3x > 6x - 27
Subtract 6x from both sides to be able to find the value of x
-3x > -27
Divide by -3 on both sides
x > 9
The answer would be the third option, since X is anything greater than 9
