Answer:

-0.119

48.577

Step-by-step explanation:

9.5x (3 + 4x) /(2 + 17x) = 138.5

19x(3+4x)/(2+17x)=277

57x+96x²=277(2+17x)

96x²+57x=554+4709x

96x²- 4652x-554=0

solving the quadratic equation:

x =(2326-√5463460)/96=(1163-√ 1365865 )/48= -0.119

x =(2326+√5463460)/96=(1163+√ 1365865 )/48= 48.577

• Chandra bought a 2-liter bottle of

frosja888 [35]

Answer:

Step-by-step explanation:

1 liter = 33.8 fl oz

Hence

2 liter = 33.8 * 2 = 67.6 fl oz

Now, we need to determine, how many 8 fl oz glasses can be filled with 67.6 fl oz of juice. For that, we need to divide total amount of juice (in fl oz) by 8. We will get:

$\frac{67.6}{8}=8.45$

So there is enough juice to fill around 8.5 glasses, but we need to know how many FULL GLASSES can be filled, NOT PARTIAL.

Thus, we can say:

8 glasses max can be filled with 2 Liters of juice
