Answer:
168 unlimited-ride passes.
Step-by-step explanation:
50x+20y=10680
x+y=282
Multiply.
20(x+y=282)
20x+20y=5640
Subtract.
50x-20x+20y-20y=10680-5640.
30x=5040
x=168
Hope this helps plz hit the crown :D
If x+y=-1, y=-x-1
You cannot solve for y in this instance.
Answer: 57
Step-by-step explanation:
28 1/2 / 1/2
make 28 and 1/2 into 57/2
so now 57/2 divided by 1/2
the same as 57/2 times 2/1
multiply straight across
(57)(2)/(2)(1)
114/2
57
100.20 < 7.40t + 41
The chemistry club can spend exactly $100.20 for 8 hours, but cannot exceed 8 hours to keep the maxed limit. So 8 hours or less
Lines that are perpendicular to another line has an opposite reciprocal slope. (opposite meaning to negate the number).
Lines that are parallel have the same slope.
But the line you provided is a vertical line, and vertical lines are undefined. There is no possible perpendicular or parallel line. Maybe you gave the wrong equation and didn't put it in <em>y=mx+b</em> form. If so, you can correct it in the comments, and if not, that's you answer!
