Answer:
A closed dot represents a lreater than or equal to or less than or equal to, which can be distinguished in an inequaity's equation by an underline.
Step-by-step explanation:
We have a problem of a sysmtem of equation
x is the number tickets sold of general admission
y is the number o tickets sold for seniors
The first equation is about the number of ticktes sold
x+y=155
the second equation is about the amount of money
12x+9y=1680
we isolate x of the first equation
x=155-y
we substitute the equatio above in the second equation
12(155-y)+9y=1680
1860-12y+9y=1680
we isolate the y
-3y=1680-1860
-3y=-180
y=-180/-3
y=60
then we substitute the value of y in order to find x
x=155-y
x=155-60
x=95
They sold 95 tickets of general admission
Answer:
0.106
Step-by-step explanation:
100 meters= 382 feet (per hour)
60 minutes in an hour
60 seconds in a minute
382/60=6.34 inches per minute (rounded to nearest tenth)
1 minute = 6.34 inches
6.34 / 60 = 0.106 (rounded to nearest thousandth)
80*0.45= 36
36*2.5mL = 90mL dosage
