Answer: 10x+16
Step-by-step explanation:
Use the distributive property a(b+c)= ab+ac
so
-2(-5x-8) = (-2 * -5x) - (-2* -8)
=
10x-(-16)
=10x+16

Answer: the cost of an adult ticket is $9.
The cost of a child's ticket is $13
Step-by-step explanation:
Let x represent the price of one adult ticket.
Let y represent the price of one student ticket.
On the first day of ticket sales, the school sold two adult tickets and three students tickets for a total of $57. It means that
2x + 3y = 57- - - - - - - - - -1
The school took and $70 on the second day by selling two adult tickets and four student tickets. It means that
2x + 4y = 70- - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
- y = - 13
y = 13
Substituting y = 13 into equation 1, it becomes
2x + 3 × 13 = 57
2x + 39 = 57
2x = 57 - 39 = 18
x = 18/2
x = 9

Answer: 3/2
Step-by-step explanation:
Just take the length of 1 side, for example LP, and count the length in units.
LP = 8 units
Now, L’P’ = 12 units, so divide the length of L’P’ by LP to get the factor of dilation.
12/8 = 3/2
A. 20 children and 10 adults
Equation 1: a + c = 30
Equation 2: 8a + c = 100
B. 10 children and 20 adults
Equation 1: a + c = 30
Equation 2: 8a – c = 100
C. 10 children and 20 adults
Equation 1: a + c = 30
Equation 2: 8a + c = 100
D. 20 children and 10 adults
Equation 1: a + c = 30
Equation 2: 8a – c = 100
