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 :)
Answer:
should be - 8
Step-by-step explanation:
-2*-2=4 4*-2=-8
No profit means P(x)=0: x³-4x²+3x-12=0
factor by regrouping: x²(x-4)+3(x-4)=0
take out (x-4): (x-4)(x²+3)=0
x=4 or x²=-3
x² is not a negative number, so x=4 is the only answer.
I found the missing choices. These are:
w(w – 2) = 48
w(w + 2) = 48
2w(w – 2) = 48
<span>2w(w + 2) = 48
</span>
The mosaic to be formed is rectangular in shape. This is deduced from the use of the terms width and length.
Area of a rectangle = length * width
length is longer than the width by 2, so length = w+2
Area of a rectangle = (w+2) * w
<span>The correct equation is: w(w + 2) = 48</span>
