So you have the equations
x + 4y = 6
x + 3y = 5
Subtract the two equations.
You get y = 1.
The only answer with a value of y = 1 is A
A is your answer.
Have a nice day! :)
Answer:
18 inches and 57 inches
Step-by-step explanation:
The diameter and the circumference of a circle are proportionate to each other.
The circumference of a circle will always be the diameter times
. We know this because the circumference of a circle is represented as

in this equation, so
.
1st option:
, this is close to 57 so it's reasonable.
2nd option:
, this isn't close to 28 at all.
3rd option:
, this isn't close to 80 at all.
So the 1st option is reasonable.
Hope this helped!
1-4 will equal -3 because if you look on a number line and move 4 to the LEFT of 1 it will take you to -3. I hope this helps you! and have a great day!
