= -w + 8
 
        
             
        
        
        
Answer:
I could be mistaken but I believe that x= 42.5
Step-by-step explanation:
To find this, you solve for 4x+10=180. 
This is because the total angle measure of line RD should be 180 degrees.
When you solve this equation, you get 42.5 for X
 
        
             
        
        
        
Answer:
figure skates will be $1 cheaper.
Explanation:
<u>given equation</u>:
- to rent figure skates : f(x) = 1.50x + 2
- to rent hockey skates : h(x) = 2x +1.5
<u>solve for rent of figure skates</u>:
 f(x) = 1.50x + 2.00
f(3) = 1.50(3) + 2.00
f(3) = 6.5
<u>solve for rent of hockey skates</u>:
h(x) = 2x + 1.5
h(3) = 2(3) +1.5
h(3) = 7.5
<u>cheaper - figure skates than hockey skates</u>:
$7.5 - $6.5
$1
