Answer:
18.75
Step-by-step explanation:
Remark
For this question, you need to set up a proportion. The ratio on each side of the equal sign is dollars over pounds.
Proportion
15/8 = x / 10 Cross Multiply
Solution
8x = 15 * 10 Combine
8x = 150 Divide by 8
x = 150/8
x = 18.75
= 7(x^2 + y^2 - 4x + 6y - 5)= 0
= 7( (x - 2)^2 - 4 + (y + 3)^2 - 9 - 5) = 0
= 7[ (x - 2)^2 + (y + 3)^2 - 18) = 0
center is at (2,-3) and radius = sqrt18 = 4.24 units
