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
Definitely the question is incomplete
Using for loop in java to print positive integers ,let say first 50 integers
So the loop is:
int i ;
for( i= 0; i<= 50; i++ ) {
print (i);
}
The looping will going to start from the 1 and stop to 50
Answer:
do the following
Step-by-step explanation:
subtract the 2nd equation from the 1st....
x-2y = 14
-(x+ 3y = 9)
______________
-5y=5
y= -1
since you know that y is = to - 1 pick the 3rd answer
Basically, they're asking you to find the slope of the given line, as well as finding how far apart each points are from one another, horizontally and vertically.
Remember, horizontal goes this way (------) and vertical goes this way (I)
(I)
(I)
a) Horizontal distance : -2
Vertical distance : 3
b) Slope :
Remember, slope is rise over run.
So, rise = vertical distance, and run = horizontal distance.
So, our slope is : -3/2
