Good evening 
Answer:
<em>a) the cost of one apple is €</em><em>0.9</em>
<em>b) the cost of one pineapple is €</em><em>5.4</em>
<em>c) the cost of two pineapples and six apples is €</em><em>16.2</em>
Step-by-step explanation:
Consider P the price of a pineapple
                A the price of an apple
 A pineapple costs six times as much as an apple means P = 6A
Mum paid €7.20 for one pineapple and two apples means P + 2A = 7.20
then
6A + 2A = 7.20
then
8A = 7.20
then 
A = €0.9   
Since P = 6A then P = 6×(0.9) = €5.4
the cost of two pineapples and six apples 
= 2P + 6A 
= 2P + P 
= 3P 
= 3×(5.4)
= €16.2
       
 
        
             
        
        
        
Ratios that are equivalent to 3:11 are 6:22 and 9:33.
Hope this helps!
        
                    
             
        
        
        
Answer:
x=175
Step-by-step explanation:
The sum of all the degrees in a triangle is 180. First, you have to rind what the third degree of the triangle is. We will call this y.
85+90+y=180
175+y=180
y=5
The floor is flat, so it will be 180 degrees, therefore, x+y=180. We can substitute 5 in for y, so 5+x=180.
So, x would be 175.
