1: Expression: 4500-2000
Answer: 2500 left to go
2: Expression: 20x
Answer: 40 centimeters
3: Expression: You can easily write and evaluate an expression based off of the terms/values used in the problem. If Stacy runs 5 miles and wants a goal of 10 miles, the expression would be 10-5 or 5+5. If Tom wants to give each of his 4 friends 2 cookies, the expression would be 4 • 2 (multiplication). If Jonny wants to give his sister half of his 50 cards, the expression would be 50 divided by 2
Answer:
You did not provide the whole question and there are many possible answers, but maybe this would help.
When you write a fraction, you just need to remember that you are writing the part over the whole.
The whole would be the number of students. In this case, the number of students is 8. The part it is asking for is the nmber of students who cleaned the tables.
So to write that in a fraction you write the part as the numerator and the whole as the denominator.
The basketball player made 25%. I found this by dividing 13 by 52 and then moving the decimal point over.

Answer:
Step-by-step explanation:
16 = 2 *2 * 2 * 2 = 2⁴
16y⁴ = (2y)⁴
x⁴ - 16y⁴ = x⁴ - (2y)⁴
= (x²)² - [ (2y)² ]²
{Use identity = a² -b² =(a +b)(a- b). Here a =x² & b =(2y)²}
= (x² + (2y)² ) (x² - (2y)² )
= (x² + 4y²) (x² - 4y²)
