Whenever you see the word "per" you can ALWAYS substitue in the word "divide".  When you see "miles per gallon", change "per" into "divided by" to get miles divided by gallons.  That is how you will solve the problem.
SO.....
300 miles ÷ 10 gallons = 30 miles per gallon
        
                    
             
        
        
        
Answer:
(28 + h + p)/4 = k
Step-by-step explanation:
Step 1: Write equation
h + p = 4(k - 7)
Step 2: Solve for <em>k</em>
<u>Distribute 4:</u> h + p = 4k - 28
<u>Add 28 to both sides:</u> 28 + h + p = 4k
<u>Divide both sides by 4:</u> (28 + h + p)/4 = k

Answer:
CE = 17
Step-by-step explanation:
∵ m∠D = 90
∵ DK ⊥ CE
∴ m∠KDE = m∠KCD⇒Complement angles to angle CDK
In the two Δ KDE and KCD:
∵ m∠KDE = m∠KCD
∵ m∠DKE = m∠CKD
∵ DK is a common side
∴ Δ KDE is similar to ΔKCD
∴ 
∵ DE : CD = 5 : 3
∴ 
∴ KD = 5/3 KC
∵ KE = KC + 8
∵ 
∴ 
∴ 
∴ 
∴ 
∴ KC = (8 × 9) ÷ 16 = 4.5
∴ KE = 8 + 4.5 = 12.5
∴ CE = 12.5 + 4.5 = 17
