the RATIO of floor seats to balcony seats in a theaters is 20:1. does this theater have more floor seats or more balcony seats?

GalinKa [24]

Yes, this theater has more floor seats than balcony seats simply because of the ratio. Your answer is actually in the question. For example, if you have 100 floor seats, then according to the ratio you should only have 5 balcony seats. So yes, there are more floor seats than balcony seats.

Help me solve this equation 3x-7=4x

Sauron [17]

Hey!

Let's write it, $3x-7=4x$
Add $7$ to both sides,
$3x-7+7=4x+7$
$3x=4x+7$
Subtract $4x$ from both sides.
$3x-4x=4x+7-4x$
$-x=7$
Since we don't want a negative variable, we have to divide both sides by $-1$ .
$\frac{-x}{-1}=\frac{7}{-1}$
Our answer would be,
$x=-7$

Thanks!
