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:
(5,2)
Step-by-step explanation:
The first coordinate is the x coordinate or the distance left or right from the origin. To get to L we go 5 units to the right or +5.
The second coordinate is the y coordinate or the distance up or down, We go 2 units up or +2
(5,2)
Answer:
Approximately 50.318 km.
Step-by-step explanation:
To find the diameter of a circle, you use the equation C = pi x d, where the d stands for diameter.
First, you'd plug in the 158 for C, so you have 158 = pi x d.
Since we are using 3.14, it would be 158 = 3.14 x d, and so then we'd divide both sides by 3.14 to isolate the variable d.
158/3.14 gives you approximately 50.3184713376, though rounded to the nearest thousandths, 50.318.
