You can graph them on Desmos, then use this attachment to find out the classification.
In the first system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.
In the second system, they're parallel lines with no solution, therefore the answer is inconsistent.
In the third system, they intersect and they have one solution, therefore the answer is consistent, independent.
In the fourth system, they're the same line and have infinitely many solutions, therefore the answer is consistent, dependent.
Are you asking for the definition of circumference? because you didn’t attach a picture or give us an equation to do.
1. Translate words into equation :
Brian= b
Natasha =n
N+3n=88 (because brian has 3x more than natasha u can rewrite b as 3n)
2. Solve : 4n=88 (divide by 4)
N=22 so natasha has 22 marbles and since b=3n, brian has 66 marbles
Answer:
Step-by-step explanation:
Convert mixed fraction to improper fraction.
÷
=
÷ 
Now use K C F method
K - Keep the first fraction
C - Change the division operation to multiplication
F- Flip the second number
