Your answer is E. $25.

First let under 12 = u, over 12 = o, and adults = a.
We can now write the equations:

2u + 3a + 3o = 174
4u + 2a = 122
a + o = 46

Because we know that a + o = 46, and 3a + 3o is in the first equation, we can multiply 46 by 3 to get what 3a + 3o equals. This makes 138.
Now we can substitute 138 into the first equation to get 2u + 138 = 174
2u = 36
u = 18

Now that we know what u equals, we can substitute it in to the second equation to get:
4(18) + 2a = 122
72 + 2a = 122
2a = 50
a = $25

I hope this helps! Let me know if you have any questions :)

The length of a rectangle is five times its width.
Vera_Pavlovna [14]

Answer:

72

Step-by-step explanation:

l = 5w

A = l*w

180 = 5w *w

180 = 5w^2

Divide each side by 5

180/5 = 5w^2 /5

36 = w^2

Taking the square root of each side

sqrt(36) = sqrt(w)^2

6 =w

l = 5w = 5*6 = 30

The perimeter is

P = 2(l+w)

P = 2(6+30) = 2(36) = 72

The linear function graphed below represents Brenda’s monthly cell phone bill based on the number of hours she uses. What is her
grigory [225]

Answer:

$12 per hour

Step-by-step explanation:

In order to find her hourly rate we have to find the amount of dollars billed per hour. To do this we can use this expression: \frac{y2 - y1}{x2 - x1}

Let's use the points (1, 27) and (2, 39) in the expression:

\frac{39 - 27}{2 -1}

Now let's simplify the expression:

39 - 27 = 12

2 - 1 = 1

The expression simplifies to 12/1, or 12. This means that Brenda is billed $12 every hour she uses her phone.

I hope this helps :)
