6 out of 20=what percent?
6/20=x%
percent means parts out of 100
x%=x/100
6/20=x/100
time both sides by 100
30=x
answer is 30% passed
100-30=70
70% is answer

Answer:
x+3y=-1
Step-by-step explanation:
y=3x-2 so m=3 old slope
the new slope must be -1/3 (opposite reciprocal of the old slope).
y-y0=m*(x-x0)
y-2=-1/3*(x-(-7))
y-2=-1/3x-1/3*7
y-2=-1/3x-7/3
3y-6=-x-7
The standard form for linear equations in two variables is Ax+By=C.
x+3y=6-7
x+3y=-1
