Answer:
C. 18:30
Step-by-step explanation:
Divide the y values (games played) by the x values (games won) to find your ratio. The ratio across each of these pairs is 1.666667...
Using the ratio provided, 18:30, divide 30 by 18.
30/18 = 1.666667...
It's a match!
Therefore, the answer is C. 18:30
Answer:
1 7/8
Step-by-step explanation:
1/4=2/8
2+2/8-3/8= 1 7/8
False. Since the probability of one side of the coin is 3/10, the other must be 7/10.
(5x)^2 + x^2 = c^2
25x^2 + x^2 =c^2
sqrt 26 x ^ 2 = sqrt c^2
x sqrt 26= c
so answer is 6x + x sqrt 26
Solve for x in 2nd equation
times -1 both sides
x-5=6y
add 5
x=6y+5
sub
5(6y+5)+4y=-26
30y+25+4y=-26
34y+25=-26
minus 25 both sides
34y=-51
divide both sides by 34
y=-3/2
sub back
x=6y+5
x=6(-3/2)+5
x=-18/2+5
x=-9+5
x=-4
(-4,-3/2) is solution
