Greater than 50:
2 x (8 + 20 - 12 / 8) is 52
Less than 10:
2 x (8 +(20 - 12)) ÷ 6 is 5.33
3/9 is your answer. 3+6=9 and there are 3 red marbles.
So slope=rise/run
rise=8
run=12
8/12=4/6=2/3
the slope=2/3
Answer:
the conversion rate to convert miles per hour to minutes per hour is 1 miles per hour = 60 minutes per mile
The slope of a line in form ax+by=c is -a/b
the yint of the line is c/b
so
-6x-5y=15
slope=-(-6)/-5=6/-5=-6/5
yint is 15/-5=-15/5=-3
slope=-6/5
yint is -3
or you could just do slope intercept and solve for y
y=mx+b
m=slope
b=yintercept
slope=-6/5
yint is -3
