Adult tickets to the fall play cost $8 and student tickets cost $4. The drama class sold 20 more adult tickets than student tick
lesya692 [45]

Hi! Welcome to Brainly! Let's solve this word problem together below! :)

Let's write this as a system of equations.

8a+4s=880

a= s+20

Let's plug our a value into the first equation.

8(s+20)+4s=880

8s+160+4s=880

We combine like terms.

12s+160=880

We subtract 160 from both sides.

12s=720

We divide both sides by 12

s=60

Now, we plug this value into the second equation.

a= 60+20

a= 80

Therefore, 80 adult tickets were sold.

I hope this helps! Have a fabulous time here at Brainly! :)

Liono4ka [1.6K]

Answer:

P = mgh

P/mg = h

We can divide both sides by mg, since both mass and gravity are being multiplied and not added.

Hope this helps!! :)
