A store sells 6 oranges for $13 . What is the cost for 10 oranges ? This is 100 points pls help ?

Approximately $21.67

Step-by-step explanation:

The cost of one orange:

13 ÷ 6 = 2.16666

The cost of 10 oranges:

2.166666 × 10 = 21.66666 ≈ $21.67

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

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
