Answer:

Option B - $y=5x+40$ and $y=3x+60$

Step-by-step explanation:

Given : The Thrill amusement park charges an entry fee of $40 and an additional $5 per ride, x. The Splash water park charges an entry fee of $60 and an additional $3 per ride, x.

To find : Which system of equations could be used to determine the solution where the cost per ride of the two amusement parks, y, is the same?

Solution :

Let x be the number of rides and

y be the cost per ride.

According to question,

The Thrill amusement park charges an entry fee of $40 and an additional $5 per ride.

The equation form is $y=40+5x$

The Splash water park charges an entry fee of $60 and an additional $3 per ride.

The equation form is $y=60+3x$

Therefore, The required system of equations form are

$y=5x+40$ and $y=3x+60$

So,Option B is correct.

Brianna and Ava go to the movie theater and purchase refreshments for their friends. Brianna spends a total of $39.00 on 2 bags

kirill [66]

Answer:

2p + 2d = 39 ____________(1)

8p + 10d = 174.50 _________(2)

Price of one drink is $9.25

Step-by-step explanation:

Let the price of a bag of popcorn be p.

Let the price of a drink be d.

Brianna spends a total of $39.00 on 2 bags of popcorn and 2 drinks. This implies that:

2p + 2d = 39 ____________(1)

Ava spends a total of $174.50 on 8 bags of popcorn and 10 drinks. This implies that:

8p + 10d = 174.50 _________(2)

We now have two system of equations which we can use to find the price of a bag of popcorn and drink:

2p + 2d = 39 ____________(1)

8p + 10d = 174.50 _________(2)

Multiply (1) by 4 subtract from (2):

8p + 10d = 174.50 _______(2)

-<u> 8p + 8d = 156 </u> __________(1)

2d = 18.50

=> d = $9.25

The price of one drink is $9.25

If f(x)=3/x+2-square root of x-3 what is f(19)

jasenka [17]

Answer:

-27/7

Step-by-step explanation:

Replace x with 19,

f(19)=3/(19+2) - root(19-3)

=3/21 - root(16)

=1/7 - 4

=1/7 - 28/7

= -27/7

Which expression gives the distance between the points (5, 1) and (9, -6)?

Vesna [10]

So the distance formula: d = rad (x2 - x1)^2 + (y2 - y1)^2
it doesn't matter what order you do, you just have to make sure it's a y coordinate for y and an x coordinate for x.
rad (9-5)^2 + ((-6)-1)^2
rad 4^2 + (-7)^2
rad 16 + 49
rad 65

Answer:

37.74

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle. The one applicable here is ...

Sin = Opposite/Hypotenuse

sin(32°) = 20/x

x = 20/sin(32°)

x ≈ 37.74
