Answer:
4 cars because he washed 20 cars in 20 hours
Whatever the answer is, you graph the answer
3x+1.5y≤25 X represents board games and each board game weighs 3 lbs (3x). Y represents remote controlled cars which each weigh 1.5 lbs (1.5y). The inequality sign (less than or equal to, ≤) is used because in total the amount of board games and remote controlled cars CANNOT exceed 25 lbs.
Answer:
12 units
Step-by-step explanation:
From the given figure, it can be seen that AB=BC, thus
From ΔBEC, using the Pythagoras theorem, we have





Now, from ΔABE, using the Pythagoras theorem, we have




Thus, the measure of AE is 12 units.
