Question

Kevin is 333 years older than Daniel. Two years ago, Kevin was 444 times as old as Daniel. Let k be Kevin's age and let d be Daniel's age. Which system of equations represents this situation? a. D=k+3 d-2=4(k-2) b. K=d+3 k-2=4(d-2) c. D−2=(k−2)+3 d=4k d. K−2=(d−2)+3 k=4d ​ ​

Answer 1

Answer:D

Explanation:

Answer 2

d. K−2=(d−2)+3 k=4d

Explanation:

Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel. Let k be Kevin's age and let d be Daniel's age. Which system of equations represents this situation?

we have to interpret the questions and write it mathematically

Let k be Kevin's age and let d be Daniel's age.

"Kevin is 3 years older than Daniel" can be mathematically written as k= d+3

"Kevin was 4 times as old as Daniel" can be mathematically written as k = 4d

Therefore the correct option is d.

k-2 =(d-2)+ 3 k = 4d

Because k-2 = d-2+3 is the same as k= d+ 3
