He should use 886 fluid ounces of soap.
<u>Step-by-step explanation</u>:
Know that 8 fluid ounces make 1 cup.
Now 24 cups need 32 fluid ounces or, 3 fluid ounces of water need 32 fluid ounces of soap.
Thus, by unitary method,
84 ounces of water need 32 × 84 / 3 ounces of soap.
Thus the answer comes to 886 ounces.
Let's call the first unknown integer x and the second one y.
"Four times an unknown integer"
"Multiplied by three times the unknown integer plus a different unknown integer"
- 4x is multiplied by 3x+y, so 4x(3x+y)=12x²+4xy
"Equals 100."
And so the answer is C: 12x²+4xy-100=0
Slope formula:
y2 - y1
_____
x2 - x1
5 + 16
_____
18 + 8
21
__
26
slope is 21/26
The answer is c because it makes the most sense
