Answer:
a) 4(x - 2) = 100
4x - 8 = 100
4x = 92
x = 23
b) 2(x - 2) = 50
2x - 4 = 50
2x = 46
x = 23
Step-by-step explanation:
 When solving for x in both equations, we get the same value of x which makes that statement true.
 
        
             
        
        
        
Step-by-step explanation:
(2$+1.5&)+0.9$X=20$
3.5$+0.9$X=20$
0.9$x=20$-3.5$
x=16.5$/.9$
x=18.333
so he can travel 18.333miles.
first we need to add the two separated cause of 1.5 Dollar in $2 tip which give us 3.5 dollar that is to be subtracted from the $20 you have. then the money that is left in your pocket is 16.5 dollar s this will be deducted 0.9 for every mile so dividing 16.5 by 0.9 gives 18.333.
 
        
             
        
        
        
820 pages X 350 words = 287,000 words 
<span>287,000 / 110 = 2.609.09 minutes </span>
<span>2.609.09 / 60 = 43.48 hours </span>

Answer:  m = 6/7n-1
Step-by-step explanation: to get 7m alone dirst we must subtract 2 from both sides so 2-2 = 0 and -5 - 2= -7 so 7m= 6n-7 and divide both sides by 7 to get m alone so 6n divided by 7 = 6/7n and -7 divided by 7 equals -1 so we're left with m= 6/7n-1
 
        
             
        
        
        
Answer: We can find out the missing statement with help of below explanation.
Step-by-step explanation:
We have a rectangle ABCD with diagonals AC and BD ( shown in given figure.)
We have to prove: Diagonals AC and BD bisect each other.
In triangles, AED and BEC.
 ( By alternative angle theorem)
 ( By alternative angle theorem)
 ( Because ABCD is a rectangle)
 ( Because ABCD is a rectangle)
 ( By alternative angle theorem)
  ( By alternative angle theorem)
By ASA postulate,
By CPCTC,  and
 and 
⇒ BE= ED and CE=EA
By the definition of bisector, AC and BD bisect each other.
