Answer:
The correct answer is C. 2.
Step-by-step explanation:
To solve this problem, we should begin with the second step and work backwards in order to find the unknown value. If given the equation -15x + 30 = 25, we should factor out a -15 to simplify. This method is shown below.
-15x + 30 = 25
-15(x-2) = 25
We know this is correct because if we redistribute the -15 through the parentheses using the distributive property, we would get our original equation again. In other words, this answer is confirmed by the fact that -15 * -2 equals positive 30.
However, we need to look closely at the question that is asked. The box that we must fill in is already preceded by a negative sign, thus the correct answer is C. 2.
We can check our work by replacing the box with the number 2, getting -15(x-2) + 30 = 25, which was the equation we got earlier.
Hope this helps!
Answer:
I am not sure on this one, sorry :(
Step-by-step explanation:
1. Reverse the numerator and denominator of the second fraction and change the division sign to a multiplication sign
2. Multiply the 2 fractions (By multiplying the numerators and the denominators).
3. Simplify is necessary.
Hope this helped!
Answer: 
Step-by-step explanation:
you would multiply by 3 on both sides to get the division to go away.
then subtract 8 from both sides.
then you have your answer
