Answer:
an=7.35+ 0.33(n-1)
Step-by-step explanation:
The relationship between women's whole-number shoe sizes and foot lengths is an arithmetic sequence, where an is the foot length in inches that corresponds to a shoe size of n.
We are given values for n=7 and n=12 as a7=9.33 and a12=11
So, we proceed from the options and check which an satisfies these values:
an = 7.35 + 0.33(n-1)
when n = 7:
an = 7.35 + 0.33 (7-1)
an = 9.33
when n = 12:
an = 7.35 + 0.33 (12-1)
an = 10.98≈11
Hence, correct option is:
an=7.35+ 0.33(n-1)

Answer:
- commutative property of addition
- distributive property
Step-by-step explanation:
6ab²+4a²b-3ab²+3a²b-2a²b²
= 4a²b+3a²b-3ab²+6ab²-2a²b² . . . commutative property of addition (twice)
= (4+3)a²b+(-3+6)ab²-2a²b² . . . . . . distributive property (twice)
= 7a²b+3ab²-2a²b²

Answer:
The solution of the system of the equation is (2, 2)
Step-by-step explanation:
Let us solve the system of equations
∵ 3x + y = 8 ⇒ (1)
∵ 3x - y = 4 ⇒ (2)
→ Add equations (1) and (2) to eliminate y
∴ (3x + 3x) + (y + -y) = (8 + 4)
∴ 6x + 0 = 12
∴ 6x = 12
→ Divide both sides by 6 to find x
∵
∴ x = 2
→ Substitute the value of x in equation (1) to find y
∵ 3(2) + y = 8
∴ 6 + y = 8
→ Subtract 6 from both sides
∵ 6 - 6 + y = 8 - 6
∴ y = 2
∴ The solution of the system of the equation is (2, 2)

so she has 39 stamps at this moment. and since she bought nine more stamps lets subtract that value to see what she had before that.
1.) 39 - 9 = 30
now she has 30. but she said that before step one she sold half of them to buy that video game. so she divided her starting number by two. so again we are going to work backwards by multiplying the number by 2:)
2.) 30 x 2 = 60!!
3.) So she started out with 60 stamps
answer is 60:)
hope i helped
