Answer:
Let n be the number
100% of a number is 15 is written as: 100% × n = 15
100% = 100 / 100 = 1
Hence
100% × n = n = 15
We now need to find 50% of the number
50% of 15 = (50 / 100) × 15 = 750 / 100 = 7.5

Answer:
5(3x + 5) or 15x + 25
Step-by-step explanation:
A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:
P = 5(3x +5)
Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:
P = 15x + 25
