Answer:
Step-by-step explanation: write the equation in the form of a proportion
2 1/2 is to 4 as something is to 3
2 1/2 / 4 = x/3
Then, cross multiply 2 1/2 x 3 or
5/2 x 3/1 = 15/2
Next cross multiply 4•X= 4X
Write as 4X = 15/2
Divide both sides by 4.
4X/ 4 = 15/2 /4
x = 15/2÷ 4/1
Divide by changing the sign to multiplication and inverting 4/1 to 1/4 like this:. 15/2. × 1/4= 15/8
Finally, 15/8 simplifies to 1 7/8 cups
Answer:
Step-by-step explanation:
a1=7
a2=13
c.d. d=13-7=6
an=a1+(n-1)d
an=7+(n-1)6=7+6n-6=6n-1
recursive formula
c.d .=an-a(n-1)
6=a_{n}-a_{n-1}
a_{n}=a_{n-1}+6
Yes it’s a regular polygon I Think
