It takes 7 minutes and 30 seconds to travel 5 kilometers because first you divide 3 and 2 to figure out how many minutes is 1 kilometer and you get 1.5 then you multiply 5 and 1.5 to get the minutes of 5 kilometers. Also the kangaroo travels 1.3 kilometers in 2 minutes
Answer:
X=20; pqr = 130°
Step-by-step explanation:
They key here is to notice that the instructions say that qs bisects pqr, meaning that it evenly cuts it into 2 pieces. So, to find x, you just solve for x in the equation 3x+5=2x+25. Then, you plug it back into either side of the equation, at which point, you should get 65. Since it is half of pqr, just double it to get your final answer of 130°
Answer:
He paid 5,000 for the old home, which was the original price of it.
And he paid 15,000 for the new home.
Step-by-step explanation
Twice the selling price of his old one, the selling price was 7,000
7,000 * 2 = 14000.
14000 + 1000 = 15000.
15,000 is three times more than he originally paid for his old home.
n Purchased a new one for 1,000 more than twice the selling price.
