Answer:
19 rides
Step-by-step explanation:
First, you have to subtract the admission cost from the total amount you possess.
$18.00
- 3.50
------------
$14.50
Next, you must divide the amount left over ($14.50) by $0.75.
$14.50 ÷ $0.75
≈ 19.33..(repeating)
Since you can't go on 1/3 of a ride, the total number of rides you may go on is 19.
Unfortunately, I can't do it on a graph here, but I will do it algebraically.
The solution on the graph will be the point of intersection of the two lines representing the equations.
y + 2.3 = 0.45x . . . . . (1)
-2y = 4.2x - 7.8 . . . . . (2)
From (2), y = 3.9 - 2.1x
substituting for y in (1), we have:
3.9 - 2.1x + 2.3 = 0.45x
2.55x = 6.2
x = 6.2/2.55 = 2.4
y = 3.9 - 2.1(2.4) = 3.9 - 5.04 = -1.2
Therefore, solution is (2.4, -1.2)
Answer:
$9.6
Step-by-step explanation:
tip $24×20% = 24×20/100 = 480/100 = $4.8
How much do they each pay ?
($24 - $4.8) : 2 = $19.2 : 2 = $9.6
The coterminal angle for the -4π/5 are -14π/5 , 6π/5 and reference angle is π/5 respectively.
<h3>What is coterminal angles?</h3>
Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.
We have an angle:
-4π/5
To find the coterminal angle, add and subtract by 2π in the angle -4π/5
Coterminal angle:
= -4π/5 - 2π
= -14π/5
= -4π/5 + 2π
= 6π/5
Reference angle:
= π - 4π/5 (as the angle lies in the second quadrant)
= π/5
Thus, the coterminal angle for the -4π/5 are -14π/5 , 6π/5 and reference angle is π/5 respectively.

Answer:
50%
Step-by-step explanation:
Let 
be equal to the decimal when multiplied by 2 equals 1
Divide both sides by 2
Multiply the decimal by 100 to get a percent
0.5×100=50%
I hope this helps!
