-q-7q=8
First you need to know that there is an invisible 1 in front of -q. Change it to -q if you need to. You get:
-1q-7q=8
add like terms: -1-7 gives you -8.
-8q=8. Divide by -8 on both sides to find q. 
-8/8=-1
8/8=1 
Therefore, q=1.
        
             
        
        
        
Given the data from the question, reaction 2 is 2.83 times faster compared to reaction 1 
<h3>Data obtained from the question</h3>
- Molarity of reaction 1 (R₁) = 0.180 mol/L
- Molarity of reaction 2 (R₂) = 0.510 mol/L
- Comparison =? 
<h3>How to determine the comparison of reaction 2 to reaction 1</h3>
We can determine how many times faster is reaction 2 to reaction by doing the following:
R₂ / R₁ = 0.510 / 0.180
R₂ / R₁ = 2.83
Cross multiply
R₂ = 2.83 × R₁ 
From the above illustration, we can see that reaction 2 is 2.83 times faster than reaction 1

Answer:

Step-by-step explanation:
Since line m is parallel to line n, therefore:
 (consecutive interior angles are supplementary)
 (consecutive interior angles are supplementary)
Solve for x
 
 
Add like terms 

Add 7 to both sides 


Divide both sides by 11


 
        
             
        
        
        
Answer:

Step-by-step explanation:
Any time a number has a negative exponent that means that the resulting number will be a fraction (ex.  ). Therefore this number is the smallest number.
). Therefore this number is the smallest number. 
Anytime a number has an exponent of 0, it will always equal 1
 
        
             
        
        
        
Answer:
i think its 4 packages
Step-by-step explanation:each package is 25 so if you get 2 its 50 + another package would be 75  so you need one more.
hope this helps
