Step-by-step explanation:

3x - y = 74

4y = x

Replace x in the first expression by 4y

3x - y = 74 ➡ 3(4y) - y = 74

12y - y = 74

11y = 74

y = 74/11 we can use this to find x

4y = x

4 × 74/11 = x

296/11 = x

PLEASE HELP!! Question with picture is below
Alenkinab [10]

Answer:

It honestly does not matter, but I'd choose the ring because I feel like it is more pleasant to look at.  

Step-by-step explanation:

We need to find the area of both shapes to compare:

3/4 of a circle:

A = 6^2pi

= 36pi

36pi(0.75) = 27pi

Ring:

A = 36pi

A2 = 3^2pi = 9pi

36pi-9pi = 27pi

As you can see, the two areas are the same.

Hope this helped! :)
