I hope my answer has come to your help. Thank you for posting your question here in Brainly.
(x,y) = (0,0) x=0 y=0 I would use the elimination method. hope this helped
Answer: 0.18 (18 cents) per ounce
Step-by-step explanation:
2.88/16 = 0.18
Step-by-step explanation:
First, we need to find that top angle, which we'll call angle x. We can say 26 is the hypotenuse, and 12 is the adjacent, so we know that:

Let's solve this, to find X:

Now that we know what X is, we can use trig to find the missing side, which we'll call y. 48 is the adjacent, and y is the hypotenuse, therefore:

To find y, let's rearrange:

And now let's figure out calculate the value of y (I'm leaving the value of X as just X for the equations, but you will need it to calculate first):
