Cost of 1 pack of trading cards = xTotal packs purchased = 10Cost of 10 packs before discount (A) = 10 * xDiscount percentage = 20 %Discount amount per pack = (20/100) * xDiscount amount for 10 packs (B) = (20/100) * x * 10Cost of 10 packs after discount is (A) - (B) = (10 * x) - ((20/100) * x * 10)Simplifying, we get x * (10 - 200/100) = x * (10 - 2) = x * 8 = 8 * xCost of shipping = $3.99Total cost of 10 packs of trading cards after discount and including cost of shipping can be represented by the algebraic expression 8 * x + 3.99 or 8x + 3.99
To find it you have to line them up for an example
2;2,4,6,8
4;4,8
And there you see a common number and its 4 and 8 if you wanted least then you would take the 4
Answer:
Estimate width of the hall is 90 feet.
Step-by-step explanation:
Given: The area of rectangular banquet hall is 7400 square feet and the length of one side of the hall is 82 feet.
To find the width of the hall.
Area of rectangular is multiply the length by width.
i,e
......[1] ; where A is the area of rectangle, l is the length and w is the width of the rectangle respectively.
Substitute the value of A = 7400 square feet and length(l) = 82 feet in [1] to solve for w;
![7400 = 82 \times w](https://tex.z-dn.net/?f=7400%20%3D%2082%20%5Ctimes%20w)
Divide both sides by 82 we have;
= 90.24 feet ≈ 90 feet.
therefore, the width of the hall is 90 feet.
Answer:
hi there my straety would be to calculate each of the intermediate values first. i.e. sqrt of 2 = 1.414213562,
Step-by-step explanation:
Answer:
Perimeter of a rectangle = 2W + 2L (where W is the width and L is the length)
Given:
- width = (-3x + 1)
- length = (2x - 5)
⇒ perimeter = 2(-3x + 1) + 2(2x - 5)
= -6x + 2 + 4x - 10
= -2x - 8
