When you are multiplying an exponent directly into a number/variable with an exponent, you multiply the exponents together.
For example:
When you are multiplying a variable with an exponent by another variable with an exponent, you add the exponents together.
For example:
You multiply 3 into each exponent in the numerator and the denominator
When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.
When you have something like this:
You subtract the exponents together, so:
Your answer is the second option
Answer:
2
Step-by-step explanation:
because 
So,
Answer:
<h2>-8(k - 4) = -8k + 32</h2>
Step-by-step explanation:
-8(k - 4) <em>use the distributive property: a(b + c) = ab + ac</em>
= (-8)(k) + (-8)(-4) = -8k + 32
For this case we can propose a system of equations:
x: Let the variable that represents the number of small cookies
y: Let the variable that represents the number of large cookies
According to the statement we have:
We multiply the first equation by -2:
We have the following equivalent system:
We add the equations:
We look for the value of the variable "x":
Answer:
They sold 80 small cookies and 50 large cookies
You can set proportions up 4 ways.
See picture. Sorry you got the wrong answer.
