13 and what other number?
48 because,
<span>For example
To find x percent of y you can just do </span>
<span>y times x/100 </span>
<span>So in this case </span>
<span>100 times 20/100 </span>
<span>which comes to 20 </span>
<span>so 20% of 100 is 20. </span>
Answer:
Part A: x^2 + 5x - 8
Part B: 5x^3 + 3x^2 - 6x + 5
Step-by-step explanation:
Part A:
To find the total of side 1 and 2, add the two expressions which represent each side. Combine like terms to simplify.
3x^2 − 2x − 5 + (7x - 2x^2 − 3)
3x^2 - 2x^2 -2x + 7x -5 + -3
x^2 + 5x - 8
Part B:
To solve for the third side of a triangle using its perimeter, subtract the lengths of two of its sides from its perimeter. The perimeter is 5x^3 + 4x^2 − x − 3. Subtract 3x^2 − 2x − 5 and 7x - 2x^2 − 3. The remaining expression is the third side. Combine like terms to simplify.
5x^3 + 4x^2 − x − 3 - (3x^2 − 2x − 5) - (7x - 2x^2 − 3)
5x^3 + 4x^2 - x - 3 - 3x^2 + 2x + 5 - 7x + 2x^2 + 3
5x^3 + (4x^2 -3x^2 + 2x^2) + (-x + 2x - 7x) + (-3 + 5 + 3)
5x^3 + 3x^2 - 6x + 5
The clearance price of hat is $17.28
Step-by-step explanation:
Price paid by store = $20
Increment = 60% of price paid
Increment = 
Increment = $12
Increased price = 20+12 = $32
Sale = 10%
Discount amount = 10% of increased price
Discount amount = 
Discount amount = $3.2
Sale price = 32 - 3.2 = $28.8
Clearance sale = 40%
Discount of clearance sale = 40% of sale price
Discount = 
Discount = $11.52
Clearance price = sale price - Discount of clearance sale
Clearance price = 28.8 - 11.52 = $17.28
The clearance price of hat is $17.28
