Answer: True, False, False, False, False
<u>Step-by-step explanation:</u>
a) 5x - 7(x - 1) 
    5x - 7x + 7
          -2x + 7   ⇒  a = -2, b = 7   <em>One Solution</em>
b) 3(x - 5) - 7
    3x - 15 - 7
        3x - 22   ⇒  a = 3, b = -22   <em>One Solution</em>
c) 2 - 7x + 3 + 4x
   4x - 7x + 3 + 2   
               -3x + 5  ⇒   a = -3, b = 5   <em>One Solution</em>    
d) -3(x - 3) - 1
    -3x + 9 - 1
        -3x + 8   ⇒   a = -3, b = 8   <em>One Solution</em> 
e) -5x + 2 + 2x + 4
    -5x + 2x + 2 + 4 
                   -3x + 6  ⇒   a = -3, b = 6   <em>One Solution</em>

Answer:
Step-by-step explanation:
To write this sentence as equation 
We get
r×338+97=r
338r+97=r
To solve further
r-338r=97
-337r=97
r=-0.2878
 
        
             
        
        
        
In a standard set of cards, the probability of drawing a red card or a face card is  73%
<h3>What is the probability?</h3>
In a standard deck of cards, there are 26 red cards. In that same deck, there will be 12 face cards. 
The probability of picking either one is:
= (Number of face cards + Number of red cards) / Number of total cards 
Solving gives:
= (12 + 26) / 52 
= 38 / 52
= 73%

If the Khans car runs 22 miles per one gallon, then on 5 gallons of gas they can drive 110 miles. 
1 gallon = 22 miles
5g x 22m = 110
