Answer:
- 0.8
Step-by-step explanation:
The first thing we want to do here is simplify the expression -
( 2x + 5 ) - 2x, Distribute the " " to elements within the parenthesis
= 
2x + 5 - 2x, Focus on simplifying the expression " 2x + 5 "
= 
- 2x
= 
- 2x, Combine fractions
= 
+ 3
= 
x + 3
So we have our simplified expression " x + 3, " with being the coefficient of x. Our requirements are that this fraction should be expressed as a decimal, so we can simply divide the numerator by the denominator to figure that out,
- 4 / 5 = - 0.8,
Solution = - 0.8

Answer:
Arianna is correct
Step-by-step explanation:
She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.
