Answer:
Picture below answers your question.
 
        
        
        
Make 2 eqn, let a be apples and o be oranges:
1. 5a + 4o = 10 
2. 5a + 5o = 11
set up an elimination:
1. minus 2.
 5a + 4o = 10
- 5a + 5o = 11
____________
 o = 1
sub “o” into one of the eqn
5a + 5(1) = 11
5a = 11-5
5a = 6
a = 6/5
a = 1.2
therefore, an orange costs $1.00 and an apple costs $1.20
        
             
        
        
        
14 
The polygon is a 14gon / it has 14 sides
        
             
        
        
        
Step-by-step explanation:
first of all you times every number with two 2(n-7) then collect like terms then divide
 
        
             
        
        
        
Answer: The resultant would be the sum and the difference between the vectors.
Step by step explanation: 1. The possible resultant is between the sum of the 2 vectors and the difference between the two vectors. 
2. The greatest magnitude is when the vectors lie in the same direction and the sum would be the scalar sum of the two vectors. The angle between the two would be zero degree.
