Answer:
Part A:
We are given that E is 3 more than D. This means that to get the value of E, we will simply add 3 to the value of D
Therefore:
E = D + 3
Part B:
We are given that F is 5 less than D. This means that to get the value of F, we will simply subtract 5 from the value of D
Therefore:
F = D - 5
Part C:
To get the value of E-F, we will simply subtract the equation we obtained from part B from the equation we obtained from part A
Therefore:
E - F = (D+3) - (D-5)
E - F = D + 3 - D + 5
E - F = 8
Hope this helps :)

Answer:
   11.6 cm
Step-by-step explanation:
As the page title tells you, the Pythagorean theorem must be applied more than once. As you know, it tells you the square of the hypotenuse is the sum of the squares of the two sides.
   AD² = ED² +EA²
   EA² = AD²-ED² = 7² -6² = 13
   EA = √13 ≈ 3.606 
__
   CD² = ED² +EC²
   EC² = CD² -ED² = 10² -6² = 64
   EC = √64 = 8
__
The length of the horizontal diagonal is ...
   AC = EA +EC = 3.6 +8 = 11.6 . . . cm
 
        
             
        
        
        
Answer:
-12
Step-by-step explanation:
-12/2 = -6
-6+15 = 9
 
        
                    
             
        
        
        
X + 4x = 75
Combine like terms:
5x = 75
Divide by 5 on each side of the equal sign:
x = 15
        
                    
             
        
        
        
Hello there! Provided the information, we know that the nearest multiple of 8 and 9 has to be greater than 50. 8 and 9 do not go into 50.
$9 • 6 hours = $54
$8 • 7 hours = $56
There are 60 minutes in an hour, so we can multiply accordingly:
60 minutes • 6 hours = 360 minutes
60 minutes • 7 hours = 420 minutes
Your final answers are:
It will take John 360 minutes to earn $50.
It will take Amber 420 minutes to earn $50.
(P.S. It takes Amber one more hour to earn $50 than it does for John to earn $50.)
Hope this helps!
