Answer:
5:7
Step-by-step explanation:
Divide by 3.
5: 7
Step-by-step explanation:
First you need to get x on one side by subtracting it from either side
Second step the side you subtracted the x to you need to get rid of the number like the number 5
Third step you need to separate the number and x since they are being multiplied to be put together you need to do the opposite and divide on both sides

B-2/3
Answer:
D. (25π - 50) sq m
Step-by-step explanation:
Since ABCD is a square with the area of 100, we know that the dimensions are 10 by 10. With that, we can find that triangle ABC = 50 sq m because of (h*l)/2. Since A is the center of the circle that contains arc BD, we know that 10 is the radius of the quarter-circle ABC. Using (πr^2)/4 to get the area of the quarter-circle, we get that the quarter-circle ABC = 25π sq m. But the original triangle ABC in the quarter-circle is not shaded. Therefore, we subtract 50 from 25π, which leads to (25π - 50) sq m.
I hope this helped! :D
