20) Answer is: x=76
21) Answer is x=15
The plane's airspeed is 140:)
Answer: You walked 12 dogs
Step-by-step explanation:
If you charge 0.75 per dog then we can represent that by the expression 0.75x where x is the number of dogs. If you charge $5 for the initial amount, then the whole expression will be 0.75x +5 and that has to equal the amount that you earned working on Saturday.So the equation will be
0.75x + 5 = 14 Now solve for x by first subtracting 5 from both sides
-5 -5
0.75x = 9 Divide both sides by 0.75
x = 12
