60 children tickets and 190 adult tickets were sold.
Step-by-step explanation:
Let the no. of adult tickets sold be 'a'
Let the no. of children tickets sold be 'c'
Total tickets sold = 250
Cost of 1 children ticket = $2.5
Cost of 1 adult ticket = $4
Total money collected= $910
Given that,
a + c = 250
a = 250 - c
4a + 2.5c = 910
Substitute a value
4(250 - c) + 2.5c = 910
1000 - 4c + 2.5c = 910
1000 - 1.5c = 910
-1. 5c = -90
1.5c = 90
c = 90/1.5
c = 60
a + c = 250
a + 60 = 250
a = 190
Step-by-step explanation:
1/2(6x+1/2)=0
3x+1/4=0
3X=-1/4
X=3(-1/4)
X=-3/4
OR
X=-.75
Answer:
Multiplying/simplifying, it is x^2-100(found by the FOIL method)
Step-by-step explanation:
multiply the commons factors x times x is x squared
-10 times 10 is -100. Negative times positive is negative.
Answer:
y=4
Step-by-step explanation:
You can ignore the 3 and 6 because this has no y value change(rise over run)
This is a straight horizontal line so the equation is y=4.
Slope=0
Answer:
x=3
Step-by-step explanation:
Vertical angles are equal so
<A = <B
7x+2 = 4x+11
Subtract 4x from each side
7x+2-4x = 4x+11-4x
3x+2 =11
Subtract 2 from each side
3x+2-2 = 11-2
3x = 9
Divide by 3
3x/3 = 9/3
x=3
