Answer:
B) 4 square root 80^x
Step-by-step explanation:
Ok. So first, we need to set up the proportion.
64/8 = x/1
Now, we can cross multiply
64*1 = 8x
64= 8x
8x/8 = 64/8
x= 64/8
Now we have to divide 64 by 8.
x=8
Our final answer: The unit rate is 8 ounces per cup.

Answer:
(x, y) = (61/23, 36/23)
Step-by-step explanation:
We assume you intend the equations to be ...
Then in general form, they are ...
5x -4y -7 = 0
2x +3y -10 = 0
The solution using the "cross multiplication method" is ...
1/(15 +8) = x/(40+21) = y/(-14 +50)
(x, y) = (61/23, 36/23)

<em>Comment on "cross multiplication method"</em>
When the coefficients from the general form equations are written as a 2×4 array with the first and last columns the same ...
the solution is 1/d1 = x/d2 = y/d3, where d1, d2, d3 are the determinants of successive pairs of columns.
- d1 = (5)(3) -(2)(-4)
- d2 = (-4)(-10) -(3)(-7)
- d3 = (-7)(2) -(-10)(5)
Answer=Order of operations
The order of operations (which we use PEMDAS to help us remember) tells you which operation to do first.
1. They both saved 65, causing a 0 dollar difference.
2. 384 ounces
explanation: 4 x 6 = 24
24 x 16oz = 384
hope this helps!
