<u>Step-by-step explanation:</u>
Here we have , Bronson is an action and horror movie junkie. He started a movie review vlog and needs to keep up with his movie viewing at a high pace. It has been a total of 50 weeks since he has stated his vlog and he has watched 1250 movies. He has watched twice as many horror movies a action movies. We need to Write two equations that can model this situation. Let's find out:
Let Bronson watched x action movies and y horror movies , than according to question horror movies he watched is twice that of action movies i.e.
⇒ ........(1)
Now , he has watched 1250 movies i.e.
⇒ .......(2)
⇒
⇒
Therefore , two equations which can model this situation is : and .
Answer:
subtract 12 from either sides:
divide either sides by -6, the inequality sign will change:
Answer:
k=-8.
Step-by-step explanation:
Step 1: subtract 14 from both sides from "2.25k - 20 =6.5k +14"
Step 2: Subtract 2.25k from both sides from "2.25k-34=6.5k
Step 3: Divide both sides by 4.25 from -34=4.25x
Your answer is k= -8.
It says -8=k.
Use the formula.
Area = (1/2)*13*10*sin(72°) ≈ 61.8 units².
