h = 6
Work Shown: 
4h + 6 = 30 
1. 4h + 6 -6 = 30 - 6 ---> 4h =  24
2. 4h /4= 24/4 ---> 6 
h = 6
        
                    
             
        
        
        
Answer:
5
Step-by-step explanation:
I drew it out on a piece of paper. R is going up and down, through PQ, which is going left to right. If the ratio is 1:3, that means that for every 1 unit there is on one side, there are 3 units in the other. If R is -1 and P is -3, they are two numbers away from each other, which means that on the other side of R (to the right of R), there needs to be 6 numbers in between to make the 1:3 ratio. R is at -1, so then you would write the equation, -1+6=? The answer is 5. 
-1+6=5 That is where Q would be
 
        
             
        
        
        
Answer:
a. 42 x 39 = 1638 ft²
b. small = 12(large)
small = 12(48)
= 576
576 - 48 = 528 more small posters
 
        
             
        
        
        
Potatoes: $2.52 / 4.5lbs = $0.56 / lb.
Broccoli: $7.75 / 2.5lbs = $3.1 / lb
Pears: $2.45 / 2.5lbs = $0.98 / lb
