5y - 3 = 3y + 27
2y = 30
y = 15
m<A= 5(15) - 3 = 75 - 3 = 72
m<B = [360 - 2(72)]/2
m<B = [360 - 144] / 2
m<B = 216 / 2
m<B = 108
Answer:67.1875%
Step-by-step explanation:
Convert ratio into fraction 86 / 128
Answer:
No, because both of them will never be able to match; become equivalent. You would have to multiply 2 different numbers to make them match, meaning they would not be proportional. For a comparison to be proportional, the ratio you are trying to simplify to must be achieved by multiplying 2 numbers from the previous ratio by one LCD.

They are<em> able</em> to make 12/21, but that does not mean they are proportional.
Answer:
Area = 9
Step-by-step explanation:
Remark
It's a right triangle. Therefore the area can be found with the two legs (a and b)
Givens
a = 3
b = 6
Area = a*b/2
Solution
Area = 3*6/2
Area = 18/2
Area = 9
Answer:
2x/2x+3
Step-by-step explanation:
2x(3x+2) over 6x 2squared + 13 x 6 = 2x (3x+2) over (3x+2) (2x+3)
