X=numerator
y=denominator
the sum of numerator and denominator=x+y
we suggest this system of equations:
y=x-3
(x+5) / (y+5)=5/6
we solve this system of equation by substitution method.
(x+5) / (x-3+5)=5/6
(x+5) / (x+2)=5/6
6(x+5)=5(x+2)
6x+30=5x+10
6x-5x=10-30
x=-20
y=x-3=-20-3=-23
Teh sum of the numerator an denominator=-20+(-23)=-43
Answer: -43
Slope-intercept form:
y=mx+b
m=slope
b=y-intercept
2x+3y=6
3y=-2x+6
y=-2/3 x+6/3
y=-2/3 x+2
Answer: the line in slope-intercept form would be:
y=-2/3 x+2
It's not specific enough to solve...so far it would only be f(3)
84 adults ; I did 108/9 = 12 then 12x7 = 84 because 9-2 = 7 and we wanted to find out the remaining number of people :))
2 is the correct answer I'm almost definite
