Answer:
B
9/12 carton
Step-by-step explanation:
Get both fractions to have the same denominator.
So make 3 into 12 by multiplying numerator and denominator by 4.
1×4/ 3×4 = 4/12
Now you can add the fractions.
5/12 + 4/12

Answer:
k = 2000
Step-by-step explanation:
To solve this equation, you need to isolate the variable k. In order to do that, you need to do the inverse operation of the constants around it - in this case, multiply 10.
k/10 = 200
To get rid of the 10, you need to multiply it on both sides in order for it to cancel out on the left:
k = 2000
Thus, k is equal to 2000
Hope this helps!
