At a Basketball Game, adult tickets are 5$ and children's tickets are 2$. If 175 tickets were sold for 686$ in total. How many of each type of ticket were sold

112 tickets for adults and 63 tickets for children

Step-by-step explanation:

In this case we can solve it using a 2x2 system of equations, like this:

let x: adult's tickets

let y: children's tickets

SW:

5 * x + 2 * y = 686

 x + y = 175 => x = 175 - y

Replacing, we are left with that:

5 * (175 - y) + 2 * y = 686

875 - 5 * y + 2 * y = 686

- 5 * y + 2 * y = 686 - 875

-3 * y = -189

y = -189 / -3

y = 63

Now to calculate x:

x = 175 - 63

x = 112

It means that there were 112 tickets for adults and 63 tickets for children

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
