Answer:
Third choice from top to bottom.
Step-by-step explanation:
The total amount of students would be exactly - 220 students. So that means reading would be exactly 20% of the students, as of 40/220 = 0.2 = 20%. That means automaticially the third choice would be correct, but let's do more calculations to make sure- 55/220 = 25%, 66/220 = 30%. That means that our answer is in fact correct.
Answer:
8x + 3
Step-by-step explanation:
Given
2(5x - 1) - (2x - 5)
Distribute first parenthesis by 2 and second by - 1
= 10x - 2 - 2x + 5 ← collect like terms
= 8x + 3
This is the additive identity property or identity property of addition.
This property states that when you add 0 to a number, the result is the original number.
