Pls help me ASAP!!! Tickets for a concert cost $7.50 for students and $15 for adults. 150 ticket are sold, and $1612.50 is colle
mariarad [96]
Answer: 85 student tickets, 65 adult tickets.
Let's say the # of students is x and the # of adults is y. The two equations we get are 7.50x + 15y = 1612.50 and x + y = 150
x = 150 - y
7.5(150-y) + 15y = 1612.5
1125-7.5y+15y=1612.5
7.5y=487.5
y=65

x=150-65
x=85

Hope this helps!

PRECAL <br><br>Find the compliment of 0.25<br><br>Find the supplement of 7π/8
balandron [24]
The unit of measurement is not specified, so for the sake of this problem, we'll assume it's radians (If you need it in degrees, I'll be happy to edit).

Find the compliment of 0.25:

Complementary angles add up to 90 degrees. In radians, this would be π/2. If you're unsure how I got this, check degrees to radian conversions.

The compliment of 0.25 would be \dfrac{\pi}{2} - \dfrac{1}{4} (1/4=0.25)

\dfrac{\pi}{2} - \dfrac{1}{4}

= \dfrac{\pi}{2} - \dfrac{1}{4} = \dfrac{2\pi-1}{4}

(This is the simplified form in case you're homework needs it in this form)

That's the compliment. In decimal (rounded to the nearest hundredth), this would be 1.32 radians.

Find the supplement of 7π/8:

Supplementary angles add up to 180 degrees. In radians, this would be π.

The supplement would be the following:

\pi- \dfrac{7\pi}{8}

=\dfrac{8\pi}{8}-\dfrac{7\pi}{8}=\dfrac{\pi}{8}

Thus, the supplement is π/8 radians. If any of this struck you as confusing, comment and I'd be happy to clarify.

Danny writes this sentence:
aliina [53]
Lets first figure out what each of the words mean in symbols.

Three less: - 3 
a number: x (you can use any variable, but the question says to use x)
five times a number: 5x
is 12: = 12

Now we need to put the equation together.

5x - 3 = 12 is the sequence that Danny wrote.
