Answer:

60.5% was the amount the zebra drank

Step-by-step explanation:

The bottle in total is 15+23=38 units

To get the % for the zebras portion you divide 23 by 38 which equals roughly 0.605 or 60.5%

edit:  1/5 of 100% is 20% which leaves 80%, 2/3 of the 80% thats left is 53.3333%

so you divide 1 by 5 which equals 0.2 or 20%, which leave 80%, then you divide 2 by 3, which equals 66.6666%, times that by the 80% (0.80 x 0.666666) equals 0.533333 or 53.333%

Therefore the Zebra drank 53.333% of the bottle

The system of equations has no solution:<br> y=2/3x-5<br> 4x - 6y = 30<br> true or false?
Serjik [45]

1. y = 2/3x - 5

2. 4x - 6y = 30

Divide 2. by 2

3. 2x - 3y = 15

Substitute 1. into 3.

4. 2x - 3(2/3x - 5) = 15

5. 2x - 2x + 15 = 15

6. 15 = 15

False. There are an infinite number of solutions.
