When writing equivalent expressions, there are often several possible orders in which to simplify them. However, they will all take you to the same result as long as you do not make a mistake when using the properties. In this example, you will distribute the outer exponent first using the Power of a Product Property.
It's simple .....
just subtract R and C.....
so 50x+10-10x-275
= 40x-265
so the answer is B
Answer:
As per the given statement: when the lights go out at the store at night there's a 15% off sign hanging out by the make up counter.
To find the number as a decimal and a fraction in simplest form.
Given the Number = 15%.
If we convert any number from percent to decimal divide by 100 and remove the % sign.

Then the given number in decimal is, 0.15
Now, to convert this percent into fraction;

Divide both numerator and denominator by 5 to get;

Therefore, the given number in fraction is;

Hence the fraction of a pie that each slice represent is: 1,8
