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)
Answer: i think its 9 but sorry if I'm wrong I'm only in 4th grade
Step-by-step explanation:
Answer:
Henry is 18 and Paul is 7
Step-by-step explanation:
I figured it out in my head.
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!
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
Hope this helps, have a nice day! :)
