Answer:
5y+6=3y+9
We move all terms to the left:
5y+6-(3y+9)=0
We get rid of parentheses
5y-3y-9+6=0
We add all the numbers together, and all the variables
2y-3=0
We move all terms containing y to the left, all other terms to the right
2y=3
y=3/2
y=1+1/2
Don't cry!! You got this! Just take it one step at a time and list your known values:
h = 5 m
r = 5 m
The volume of a cone is V = (1/3)πr^2h
V = (1/3)(3.14)(5)^2(5) = 130.83 m^3
I believe in you! I hope this helps!

Answer:</h3>
(m, a, b, c) ∈ {(1, 196, 441, 210), (7, 28, 63, 30)}
<h3>
Step-by-step explanation:</h3>
m is a common factor of 196, 210, 441
The prime factors of those numbers are
... 196 = 2²×7²
... 210 = 2×3×5×7
... 441 = 3²×7²
7 is the only prime factor common to all the numbers. Hence the possible values of m are 1 and 7.
For m = 1, (a, b, c) = (196, 441, 210).
For m = 7, (a, b, c) = (196, 441, 210)/7 = (28, 63, 30).
