Hi there! The answer is y = -2

First we collect terms.

Now we add 3 to both sides of the equation.

Finally we divide both sides by 11.

Hence, the answer is y = - 2
Answer:
A. 13%
Step-by-step explanation:
let's suppose there's 1000 bars of chocolate in general
70 % dark = 700 dark choco bars
30 % milk = 300 milk choco bars
20 % have nuts = 200 bars have nuts
80 % don't have nuts = 800 bars don't have nuts
if 90 % of dark chocolate bars don't have nuts, that means 630 dark chocolate bars don't have nuts, but 70 have nuts
200 bars in general have nuts, if only 70 dark chocolate bars have nuts,
200 - 70 = 130
130 = 13%
Answer: 217.6
Step-by-step explanation:
64% is a fraction of 100, so it would be 64/100.
Multiply that by 340.

You can also do 340 * 0.64 for the same result.
