Which of these formulas models this arithmetic sequence?

5.9, 5.5, 5.1, 4.7, 4.3, . .

an = -0.4 + (n – 1) × 5.9

an = (n – 1) × (-0.4)

an = 5.9 + (n – 1) × (-0.4)

an = 5.9 + (n – 1) × 0.4

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
