Answer:
time walking=1-t hrs
ditace is same
therefore 2.5*(1-t)=45*t
2.5-2.5t=45t
t=2.5/46.5 hrs
this has only one solution since it is in linear form
Multiply 1.5 times 7. That comes to 10.5 cups per week. Now convert it to quarts. There are 4 cups in one quart, so divide 10.5 by 4. That comes to 2.625 quarts per week. Now convert it to gallons. There are 4 quarts in a gallon, so divide 2.625 by 4. That comes to about 0.7 gallons a week, or 7/10.
<span>The 53 bicycles are the bicycle brand of playing cards. Since we all know that a deck contains 52 cards, he must have been cheating and he put another card in the deck. His buddy caught him and killed him</span>
8x + 47 = 8x + 40
No solutions (the above 2 expressions cannot be equal for any value of x)
