Answer:
x = 9
Step-by-step explanation:
50+80+(6x-4)=180 (ANGLE SUM PROPERTY)
130 +(6x-4)=180
6x-4=180-130
6x-4=50
6x=50+4
x=54/6
x = 9
 
        
             
        
        
        
A. The number of 10-boards Peter bought is equal to n divided by 10. Then, each of the 10-boxes will get two boxes of nails. The number of boxes of nails that Peter will have after buying n boards will be,
    N = (2)(n/10)
Simplifying,
<em>   N = n/5</em>
b. If the number of boards are 90 then,
     N2 = (90/10)(2)(100 nails/box)
     N2 = 1800
Answer: 1800
        
                    
             
        
        
        
Answer:
A
Step-by-step explanation:
Since the total cost at first will not be 5 exactly, it will turn to 4.5 (4.50). And it will be just below the five, at the first hour. And then from there, just add 3.25 each hour and forget about the 1.25 since 1.25 is used for the beginning only, and not the rest.

Well, 99 times 10 is 990, 990 plus 9 is 999. If you understand pls respond
        
             
        
        
        
 Equations:
100 + 35m 
50 + 35m
Steps:
100 + 35m = 50 + 35m <span>
<em>Set the equations equal to each other.</em>
</span>   <span />
<span>
100 + 35m = 50 + 35m <span>
-50              - 50
</span>
<em>Subtract 50 from both sides of equation to isolate the variable on one side</em>. 
50+35m=35m
     -35m  -35m
<em>Subtract 35m from both sides of equation.</em>
50=m
