Step-by-step explanation:
consecutive numbers follow each other thus if the first is x the second will be x+1 e.t.c:
1. x+x+1+x+2+x+3=2
x+x+x+x+1+2+3=2
4x=2-6
4x= -4
x= -1
The numbers are -1, 0, 1 and 2
2.x+x+1+x+2= -6
3x+3=-6
3x= -6-3
3x= -9
x=-3
The numbers are -3,-2 and -1
Answer: 40 tickets.
Step-by-step explanation:
Let's call:
x: the number of child tickets sold that day.
y: the number of adult tickets sold that day.
Based on the information given in the problem, you can make the following system of equations:
You must use the method of substitution to solve the system of equations:
Substitute y=3x into the second equation and solve for x:
Then the answer is: 40 tickets.

Answer: The answer is A ($19)
Step-by-step explanation:
The total amount spent between the two person = $47.5
If Hector is represented by H
Francis represent by F
Therefore equation 1 = H + F = 47.5
H +F = 47.5 ..........(eqn 1)
From the question
Hector = Francis + 50% Francis
Translating this into an equation we get,
H = F + 0.5F ...... (eqn 2)
Substitute equation 2 into equation 1, we get:
(F + 0.5F) + F = 47.5
Thus 2.5F = 47.5
F = 47.5/2.5 = 19
Since Francis spend is represented by F, the amount spent by Francis is therefore $19 as obtained from our calculation.
