Minus a from both sides
x-a=-2by²
times both sides by -1
a-x=2by²
divide both sides by 2b
\frac{a-x}{2b}=y^2
sqrt both sides
y= \sqrt{\frac{a-x}{2b}}

Answer:

minus a from both sides

x-a=-2by²

times both sides by -1

a-x=2by²

divide both sides by 2b

sqrt both sides

some friends went to a local movie theater and bought four large buckets of popcorn and six boxes of candy.The total for the sna
WARRIOR [948]

The total of 2 buckets of popcorn and 3 boxes of candy would be $23.25

To answer this question you need to form a set of simultaneous equations and solve them. We can do this by saying that a bucket of popcorn = P, and a box of candy = C. Then we can say:

4P + 6C = 46.50

P + C = 9.75

There are then two possible ways to solve; you can either say that C = 9.75 - P using the second equation and then substitute it into the first, or you can multiply the second equation by either 4 or 6 to cancel out P or C.

I’m going to multiply the second equation by 4:

4P + 4C = 39

Now we can subtract this for, the first equation:

4P + 6C = 46.50

4P + 4C = 39

2C = 7.50

C = 3.75

Now we can substitute this value of C into one of the equations to find P:

P + C = 9.75

P + 3.75 = 9.75

P = 6

And now to answer the question, you just multiply P by 2 and C by 3 and add them together, which gives you $23.25

I hope this helps! Let me know if you have any questions :)

Can someone explain how to do this? I don't get it.
mihalych1998 [28]

Answer: I think 91.9

Step-by-step explanation:

If I remember right, all the angles of a triangle add up to 180 degrees. So taking 22.8 + 65.3 = 88.1, then 180 - 88.1 = 91.9

Sorry if that’s not right! I just wanted to take a crack at it.
