The answer is 18.13
(145/8) ÷ 2 » 18.125 ÷ 2 = 9.0625 is how I get this answer
2x+4y = 1
3x- 5y = 7
Multiply both equation by a number to get rid of one variable I used y because it had opposite signs so multiply top equation by 5 and bottom by 4
you get,
10x + 20y = 5
12x - 20y = 28
solve the equation we get,
22x = 33
x = 33/22
x = 1.5
substitute this value in other equation to get y
2x + 4y = 1
2(1.5) + 4y = 1
3 + 4y = 1
4y = 1-3
4y = -2
y = -2/4
y = -0.5
so answer is x = 1.5 and y = -0.5
( 1.5, -0.5)

Answer: c) P(C) = 1/3
<u>Step-by-step explanation:</u>
P(A) + P(B) + P(C) = 1 <em>(100%)</em>
P(A) = P(B) =P(C)
Using substitution:
P(C) + P(C) + P(C) = 1
3 P(C) = 1
P(C) = 1/3
