Type 1 rice :
7-ounce package costs = 2.59.
Cost of 1-ounce of Type 1 rice= 2.59/7 = $0.37
Type 2 rice :
12-ounce package costs = $4.56
Cost of 1-ounce Type 2 rice = 4.56/12 = $0.38
Type 3 rice :
18-ounce package costs = $ 6.30
Cost of 1-ounce Type 3 rice = 6.30/18 = $0.35.
From the above calculations, we can see that the cost of 1-ounce Type 3 rice is lowest. Therefore, 18-ounce package is Best Buy.
Let the number be x
Form the equation : 5x + 1 ≤ 10
5x ≤ 10-1
5x ≤ 9
X ≤ 9/5
so X can be 9/5 or any values smaller than that.
hope this helps :)
12(.25)= 3. 12-3= 9 for student tickets
x = adult tickets
y = student tickets
x + y = 55
12x + 9y= 585
-12x - 12y = -660
-3y = -75
3y = 75
y = 25 student tickets
x + 25 = 55
x = 30 adult tickets
Answer:
(3x + 2)(9x^2 - 6x + 4)
Step-by-step explanation:
Simple Question.
27x^3 + 8 = (3x)^3 + (2)^3
You can now apply the sum of the cubes formula:
x^3 + y^3 = (x + y)(x^2 - xy + y^2),
(3x)^3 + (2)^3 = (3x + 2)(3^2x^2 - 2*3x + 2^2)
= (3x + 2)(9x^2 - 6x + 4)
Solution: (3x + 2)(9x^2 - 6x + 4)
