PLEASE HELP ME!
Leya [2.2K]

Answer:

54


Step-by-step explanation:

Let number of adult tickets sold be a

Let number of children tickets sold be  c


<u>139 tickets were sold:</u>

we can write:

a+c=139


<u>a total sales of $972.00:</u>

we can write:

5.4c+9.5a=972


Now solving for c in the first equation and substituting that into 2nd equation, we can solve for a, what we need. So:

c=139-a\\-------\\5.4c+9.5a=972\\5.4(139-a)+9.5a=972\\750.6-5.4a+9.5a=972\\-5.4a+9.5a=972-750.6\\4.1a=221.4\\a=54


Hence 54 adult tickets were sold.

A map uses 5cm to mean 24 miles. How many miles matches 13cm?
Doss [256]

Answer:

62.4 miles

Step-by-step explanation:

The way to determine this is to set up a proportion,

5 cm/24 miles = 13 cm/x miles,

and then solve for x by cross multiplying,

5*x = 24*13.

<em>If you don’t understand that step, try writing it out on paper with fractions instead of division signs.</em> Next, solve.

x = 62.4
