1 hr 2 hr but im prob wrong btw james won
Step-by-step explanation:
1+2+8= 11
And she likes 8 out of the 11 tracks
So the probability is 8/11 or about 73%
Answer:
20 rides
Step-by-step explanation:
Let x represent how many rides you take.
Option A's cost can be represented by 0.8x + 30.
Option B's cost can be represented by 2.3x.
Set these expressions equal to each other, then solve for x:
0.8x + 30 = 2.3x
30 = 1.5x
20 = x
So, the costs will be the same at 20 rides
Answer:
y = 2x + [-3]
Step-by-step explanation:
Slope of the perpendicular line = m = 2
Point = (x,y) = (6,9)
So, x = 6, y = 9
Putting in slope intercept equation
![y=mx+c](https://tex.z-dn.net/?f=y%3Dmx%2Bc)
9 = (2)(6) + c
c = 9-12
c = -3
Putting m and c in slope intercept equation
y = 2x + [-3]
First, we must let:
x = number of tickets intended for adults
y = number of tickets intended for children.
a. Write in terms of x the number of tickets for children
Solution:
x + y = 28 ⇔ y = 28 - x (equation 1)
To answer in terms of x:
no. of tickets for tickets for children = 28 - x
b. the amount spent on tickets for adults
Solution: $30 is the cost of ticket per adult and there are x number of tickets intended for adults.
Therefore,
amount spent on ticket for adults = 30x
c. the amount spent on the tickets.
Solution:
$ 15 = cost of ticket per child
$ 30 = cost of ticket per adult
total amount spent on tickets = 30x + 15y ⇒ (equation2)
substitute equation 1 to equation 2.
(equation 1) y = 28 - x
(equation 2) total amount spent on tickets = 30x + 15y
total amount spent on tickets = 30x + 15(28-x)
total amount spent on tickets = 30x + 420 - 15x
total amount spent on tickets = 15x + 420
