The answer is b its easy i had this one
Not really sure how to answer this hope someone helps you!
Answer:
1. True
2. False
3. True
4. False
5. True
Step-by-step explanation:
1. For a real number a, a + 0 = a.
This is true, any number plus zero is that number.
2. For a real number a, a + (-a) = 1.
This is false. Adding a negative number is the same as subtracting that number. So a + (-a) = a - a = 0
3. For a real numbers a and b la-bl = |b-al.
This is true. Absolute value represents the distance between two numbers. This number can never be negative, therefore la-bl = |b-al.
4. For real numbers a, b, and c, a +(bº c) = (a + b)(a + c).
False. a + (b * c) = a + bc.
If you foil (a + b)(a + c) you will see its equal to a²+ab+ac+bc, which is definitely different than a + (b*c)
5. For rational numbers a and b when b# o, is always a rational number.
True, a rational number is one that can be written as a fraction with two integers. The quotient of two rational numbers can always be written as a fraction with integers.

Answer: the fraction 1/9</h3>
It is approximately equal to 0.1111
=================================
To get this answer, we use the rule
The negative exponent tells us to apply the reciprocal to get the exponent to be positive.
So,
Squaring -3 means you square the negative as well
104 total - 32 cookies = 72 brownies.
Ratio of A to B is A/B.
So ratio of brownies to cookies is 72 brownies / 32 cookies = 2.25
