Answer: 11/4
or 2.75
Step-by-step explanation:
Like terms are terms that have the same variable no matter the coefficient value such as a negative or positive coefficient (number right to left of the variable aka the letter representing an unknown amount of value).
A. 8n : - 4n becuase the have the same variable (N)
B. - 2d: D because they have the same variable and even if d has no coefficient, it still has value, variables with no coefficient always equal 1 no matter the circumstances
C. - b: 17b and -3b2 because they both have the same variable eliminating the coefficients being two different types of numbers (positive and negative). The expressions have to have the same variable.
D: 4y², -3y2,4y, and 4 to the second power. This is because they all have the same variable.
E. 6x2y: 3xy because the variable are specifially xy and they must be in order to be like terms.
abc: all because they have all the letters but are just in different orders of variables. (thats all)

Answer:
ellen ran faster
Step-by-step explanation:you take the meters ran and devide the number by an amount that would make both the meters ran the same in this case its 400 devided by 2 to give you 200 and because lindsays metres were divided then that means that you devide her time by the amount that you used to devide the metres meaning you devide her time by 2 sixty devided by 2 gives you thirty with ellans 28 sec per 200 metres and lindsays 30 sec per 200 metres than that means that ellan got to 200 metres faster than lindsay.
