Answer:
20 goes into 110 five-and-a-half times
Step-by-step explanation:
Let's show our work:
 20  +  20  +  20   +  20  +    20   +  10       
   \____\_____\____/_____/_____/ 
                            100
100
= 20 + 20 + 20 + 20 + 20 + 10
Half of 20 = 10
The keyword is half - so that leaves a 0.5 in your answer to "How many times does 20 go into 110."
How many 20's are there? Let's count!
20 + 20 + 20 + 20 + 20
  1      2       3      4       5
So five 20's + one 0.5 = ?
That equals 5.5, because 5 + 0.5 = 5.5
Your answer is 5.5!
I hope this helps!

Answer:
b
Step-by-step explanation:
 
        
             
        
        
        
To solve for x, you need to isolate/get x by itself in the equation:
 Square ² both sides to get rid of the square root √
       Square ² both sides to get rid of the square root √

x - 2 = 0           Add 2 on both sides
x - 2 + 2 = 0 + 2
x = 2
 
        
             
        
        
        
Answer:
No real roots
Step-by-step explanation:
Given
7x² + 5x + 1 = 0 ← in standard form
with a = 7, b = 5, c = 1
To determine the nature of the roots use the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then roots are real and distinct
• If b² - 4ac = 0 then roots are real and equal
• If b² - 4ac < 0 then the roots are not real
Here
b² - 4ac = 5² - (4 × 7 × 1) = 25 - 28 = - 3
Thus the 2 roots are not real
