For this case, we propose a system of two equations with two unknowns.

Let:

x: Represents the number of children's tickets

y: Represents the number of adult tickets

5.20x + 8.60y = 931.20\\x + y = 132

So, we clear x from the second equation:

x = 132-y

We replace in the first one.

5.20 (132-y) + 8.60y = 931.20\\686.4-5.20y + 8.60y = 931.20\\-5.20y + 8.60y = 931.20-686.4\\3.4y = 244.8\\y = \frac {244.8} {3.4}\\y = 72

<em>72 adult tickets were sold. </em>

x = 132-y\\x = 132-72\\x = 60

<em>60 tickets for children were sold </em>

Answer:

60 tickets for children

72 adult tickets

Answer:

60 child tickets and 72 adult tickets

Step-by-step explanation:

Let x denote the number of child tickets sold and y the number of adult tickets sold. The problem involves solving the following system of linear equations; x+y=132 and 5.2x+8.6y=931.2. Using technology to solve this simultaneous equation yields; x= 60, y =72

20 POINTS: solve for x.
lara [203]

Answer:x=7

Step-by-step explanation:

Here AD=6

AB=6 (tangents drawn from external point to a circle are equal)

Then BC=13-6=7

Now, CE=BC=7(tangents drawn from external point to a circle are equal)

EF=14-7=7

EF=FG=x=7(tangents drawn from external point to a circle are equal)
