Answer: d. s ≥ 23
Step-by-step explanation:
Let s be the side of the square.
We know that the perimeter of a square =4s
Let f(s)=4s
If the cardboard should have a perimeter equal to at least 92 inches, the inequality would look like

Divide both sides by 4, we get

Thus, d. is the right answer. The reasonable domain of f(s) is 
Answer: You paid 3/4 of the full price.
Explanation: Total cost of the two shirts = shirt one ($12) + shirt two (half price, so $6) or $18 all together. If you had paid full price for both shirts, it would have cost you $24, or $12 times 2. 24 - 18 = 6, so you saved six dollars. 24 (full price) divided by 6 = 4, so we know that $6 is 1/4 of the full price. Because of this, we know that the amount you spent ($18) was 3/4 of the full price, since 4/4 (total) - 1/4 (amount saved) = 3/4 (amount spent). Another way to solve this is to simply divide 18 by 24.
There was a total of 71,115 people who attended the different events in the arena for the past two months,
The estimated average ticket price is $ 21.15.
We need to solve for the estimated arena's ticket sale income and the solution is shown below:
Ticket Sale Income = 71, 115 * $21.15
Ticket Sale Income = $1,504,082
No it is not, this is because .634 does not have a whole number
Answer:
x = -3/10
Step-by-step explanation:
Solve for x by substituting y = 3x into the other equation:
2x - 4y = 3
2x - 4(3x) = 3
Simplify and solve for x:
2x - 12x = 3
-10x = 3
x = -3/10
So, x = -3/10
