To organize 169 students in a square formation, we find the square root of 169, which is 13, so there should be 13 students in each row.
The question pertains to arranging 169 students in a square formation for a photo. When we arrange anything in a square formation, we are essentially arranging them equally in rows and columns. Therefore, by taking the square root of the total number of students, which is 169, this will tell us the number of students that should be arranged in each row and the number of rows required.
A square root of a number is that value which, when multiplied by itself, gives the original number. The square root of 169 is 13. So, for a square formation, there should be 13 students in each row.

Use substitution to solve the linear system of equations and
determine how many chickens, x, and pigs, y there are.
Express the solution as an ordered pair (x,y).
Answer:
(6, 7)
Step-by-step explanation:
x+y= 13
2x+4y= 40 ⇒ x+2y = 20 ⇒ 13-y +2y= 20 ⇒ y= 20-13= 7
x= 13-y= 13-7= 6
chickens= 6
pigs= 7
To solve the problem, set up a system of equations using the given information. Solve one equation for a variable and substitute it into the other equation to find the values of the variables. Determine the number of chickens and pigs in the barn. The solution is (6, 7).
To solve this problem, we can set up a system of equations based on the given information. Let x represent the number of chickens and y represent the number of pigs. From the information given, we can write two equations: x + y = 13 (equation 1) and 2x + 4y = 40 (equation 2).
Using substitution, we can solve equation 1 for x and substitute it into equation 2:
Equation 1:
x + y = 13
x = 13 - y
Equation 2:
2(13 - y) + 4y = 40
26 - 2y + 4y = 40
2y = 14
y = 7
Now, substitute the value of y back into equation 1 to find x:
x + 7 = 13
x = 6
Therefore, there are 6 chickens and 7 pigs in the barn, which can be expressed as the ordered pair (6, 7).

|80 - 5x| ≤ 4
He is buying 5 tickets.
He wants his total cost to be in the range of 80 ± 4.
5x - 80 ≤ 4
5x ≤ 84
x ≤ 16.8
5x ≥ 76
x ≥ 15.2
5x - 80 ≤ 4 and 80 - 5x ≤ 4
we can express this inequality as;
|80 - 5x| ≤ 4

To model the cost x, in dollars, of a concert ticket, the inequality 80 - 4 ≤ x ≤ 80 + 4 can be used.
To model the cost x, in dollars, of a concert ticket, we can write the following inequality:
80 - 4 ≤ x ≤ 80 + 4
This inequality states that the cost of a ticket, x, must be between $76 and $84 (inclusive),
in order for Jamie's total cost for 5 tickets to be no more than $4 above or below $80.
