Tickets for wisconsin state fair cost $13 for adults and $7 for children. After the first day, the wisconsin state fair sold 900
sergiy2304 [10]
First, let's define your variables!

x=cost of tickets for adults
y=cost of tickets for kids...

You know that they sold 900 tickets, which means the combination of x and y equals 900.
Therefore one equation is...
x+y=900
We also have to take care of the second equation...
We know that 13x represents the total cost of ADULT tickets
We know 7y represents the total cost for the children...
Which means...
13x+7y=11000
There are you equations! (bolded)

I got a pic plz help​
tensa zangetsu [6.8K]

Answer:

For the first one, you get x<7.

For the second one, you get x >_ 11

Step-by-step explanation:

For the first one: -2x - 2 > -16

Step 1. Add 2 to both sides.

-2x - 2 +2 > -16 + 2

-2x > -14

Step 2. Divide both sides by -2 and switch the sign

-2x/-2 > -14/-2

x < 7

For the second one: 2x - 1 >_ 21

Step 1: Add 1 to both sides

2x -1 +1 >_ 21 + 1

2x >_ 22

Step 2: Divide both sides by 2

2x/2 >_ 22/2

x >_ 11

hope this helps!

vovangra [49]

Answer:

The large number is 17

Step-by-step explanation:

x+y=31⟹x=31−y

2x=y+11⟹x=y+11/2

2(y+11/2)=2(31−y)

y+11=62−2y

3y=51

y=17    x=14
