If sound travels through air at around 13 of a kilometer per second, and thunder is heard 6 seconds after a flash of lightning, it would be 78ths of a kilometer. Although, I can't simplify that for you. Sorry. ^-^

Answer:
24x / 5y
Step-by-step explanation:
Given :
24x² / 5xy
24x² = 24 * x * x
5xy = 5 * x * y
Hence,
24x² / 5xy = (24 * x * x) / (5 * x * y)
= (24 * x) / (5 * y)
= 24x / 5y
Answer:
0.77
Step-by-step explanation:
-0.7(-1.1) features two negative signs; (-1)^2 = +1, so -0.7(-1.1) must be positive.
Then we have 0.7(1.1). We can rewrite this with the decimal points moved as follows:
7(0.1)(11)(0.1)
7 times 11 is 77; 0.1*0.1 = 0.01
Therefore a simpler but equivalent expression is 77(0.01) or 0.77.
