Answer:
The correct answer is:
In Step 1, the student should have used One-half x to represent Nadra’s age, and written the equation (x + 3) + x + one-half x = 33.
Step-by-step explanation:
Lets solve the problem step by step correctly
Let x be the age of Kareem
Let s be sadie's age
n be Nadra's age
According to "Sadie is 3 years older than Kareem"
And According to "Kareem is twice as old as Nadra"
x = 2n
n = x/2
Step 1: Writing the equation
Step 2: Solving the equation:
Step 3
Kareem's Age = 12
Sadie's Age = x+3 = 12+3 = 15
Nadra's Ade = 12/2 = 6
The student made the error in Step 1 where he wrote the equation.
Hence,
The correct answer is:
In Step 1, the student should have used One-half x to represent Nadra’s age, and written the equation (x + 3) + x + one-half x = 33.
