Answer:
Solving for t : t=5+2r/5
Solving for r : r=-25/2+5t/2
Step-by-step explanation: Move all of your terms that don't contain r to the right side and solve. Move all terms that don't contain t to the right side and solve.
Hope this helps you out! ☺ I just solved it and I don't have any choices to go off of and so I just solved it. Sorry if it's wrong. ☺
Answer:
The solutions are 3 and -5
Step-by-step explanation:
x+3=x^2+3x-12
x^2+2x-15
=(x-3)(x+5)
He needs to learn >10 new plays, but has already learned 4. Therefore, the inequality is x+4>10, where x is the amount of new plays he must learn, 4 is the amount he has already learned and >10 (more than 10) is the amount of plays he needs to learn in total.
x+4>10
x>6 is the solved inequality
