Its a because you will add 1.25 and 0.75 because it says each and of course 18 would be what it equals
        
                    
             
        
        
        
Answer: 
The  sequence  is:
10, 30, 50, 70, 90..................... 
Step-by-step explanation:
We have,
First term (a) = 10
Common difference (d) = ?
Sum of first 5 terms ( ) = 250
) = 250
or, ![\frac{n}{2} [{2a+(n-1)d}] = 250](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B2%7D%20%5B%7B2a%2B%28n-1%29d%7D%5D%20%3D%20250)
or, ![\frac{5}{2} [2*10 + 4d]=250](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D%20%5B2%2A10%20%2B%204d%5D%3D250)
or, ![\frac{5}{2} * 4[5+d]=250](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D%20%2A%204%5B5%2Bd%5D%3D250)
or, 10(5 + d) =250
or, 5 + d = 25
∴ d = 20
Now,
2nd term = a + d = 10 + 20 = 30
3rd term = a + 2d = 10 + 2*20 = 10 + 40 = 50
4th term = a + 3d = 10 + 3*20 = 10 + 60 = 70
5th term = a + 4d = 10 + 4*20 = 10 + 80 = 90
 
        
             
        
        
        
Subtract 33 from both sides
6x>3x+30-36x>3x+30−3
  Simplify 3x+30-33x+30−3 to 3x+273x+27
6x>3x+276x>3x+27
  Subtract 3x3x from both sides
6x-3x>276x−3x>27
Simplify 6x-3x6x−3x to 3x3x
3x>273x>27
Divide both sides by 3
3x>\frac{27}{3}x>
3x> 27
  
Simplify \frac{27}{3}

Answer:
About 2.17 feet. 
Step-by-step explanation:
Let <em>d</em> represent the diameter of the tire. 
Then the circumference of the tire will be: 

So, the tire will travel dπ miles after one rotation. 
After 775 rotations, the total miles traveled should be 5280 feet. Thus: 

Solve for <em>d:</em>
<em /> <em />
<em />
Approximate: 

The circumference of the tire should be about 2.17 feet. 
 
        
             
        
        
        
Answer:
   4x +y = 3
Step-by-step explanation:
Perpendicular lines have slopes that are the negative reciprocals of one another. When the equation of the line is written in standard form like this, the equation of the perpendicular line can be written by swapping the x- and y-coefficients and negating one of them. Doing this much would give you ...
   4x +y = (constant)
Note that we have chosen to make the equation read 4x+y, not -4x-y. The reason is that "standard form" requires the leading coefficient to be positive.
Now, you just need to make sure the constant is appropriate for the point you want the line to go through. So, it needs to be ...
   4(2) +(-5) = constant = 3
The line of interest has equation ...
   4x + y = 3
