Answer:
y =34
x = 25
Money made from flight x = 3000
Money made from flight y = 9520
Step-by-step explanation:
Tickets sold
59= x+y
Amount of money
120x + 280y = 12520
Using substitution
x = 59-y
120( 59-y) + 280y = 12520
7080 - 120y +280y = 12520
Combine like terms
160y +7080 = 12520
Subtract 7080
160y = 12520-7080
160y =5440
Divide by 160
160y/160 = 5440/160
y =34
Now find x x = 59-y = 59-34 =25
x = 25
Money made from flight x =
120*x = 120*25 =3000
Money made from flight y =
280*y= 280*34=9520
-3 + [(36/9) - 3] × (-2)
First solve Parenthesis:
* -3 + [4-3] × (-2)
** -3 + (1) x (-2)
Second solve multiplication:
*** -3 + (-2)
Third step, solve addition/substraction:
**** -3-2= -5
So your answer si -5
Answer:
Step-by-step explanation:
3 x 4 = 12
this is the answer
You have to calculate the sum of 20 + 20/3 + 20/ 9 + 20/27 + 20/ 81 + ...
That is a geometric series with first term 20 and r = 1/3.
Now you can use the formula for the sum of a geometric series:
∑ Ai from i = 0 to i = A / ( 1 - r), where A is the first term.
=> 20 + 20/3 + 20/ 9 + 20/27 + 20/ 81 + ... = 20 / ( 1 - 1/3) = 20 / (2/3) = 20*3/2 = 30.
Answer: 30 feet.
