A movie theater charges $10 for adult tickets and $7 for child tickets. On a particular day, they made $1446 in ticket sales. Th

X = adults
Y = child

X+y=168
X=168-y

$10x + $7y = $1446

10(168-y) + 7y = 1446
1680 - 10y + 7y = 1446
-3 y = -234
Y = 78

X = 168-78
X = 90

$10*90 + $7*78 =
$900 + $546 = $1446

A board that measures 3/4 feet long is cut into 6 equal pieces. What is the length of each piece?

Answer:

See below:

Step-by-step explanation:

So we know that there is a $\frac{3}{4}$ feet long board and that it is split into 6 pieces.

With that information, we can split it by doing the following:

1. $\frac{3}{4} *\frac{1}{6}$

We can do this because we have a board that is 0.75 feet long and we multiply it by one sixth because we want to divide a fraction and to do that we have to flip the fraction.

After doing that, we get our answer of $\frac{3}{24}=\frac{1}{8}$
