Answer:
y=6 is the correct answer
Answer 18 2/7
Explanation: First put the fractions in improper form 5 5/7 is 40/7 and 3 1/5 is 16/5 then multiply which equals 640/35 then divide that by 5 which equals 128/7 then do 128 divided by 7 and take the whole number which is 18, do 18 times 7 which equals 126 so final answer is 18 2/7
78.5= (3.14)r^2
25=r^2
5=r
So, the radius of a circle with an area is 78.5 cm^2 is 5 cm^2
The value of x that makes the equation true can be found by multiplying both sides of the equation by 7.
x = 70
