We use the formula : Displacement = Average Velocity * Time ;
17 = ( v + 8 ) * t ;
1 = ( v - 8 ) * t ;
where v = the velocity of the boat; t is the time from expression " ... in the same amount of the time he rows ....."
Then 17 / 1 = (v + 8) / ( v - 8 ) ;
v + 8 = 17( v - 8 );
v + 8 = 17v - 136 ;
144 = 16v ;
v = 144 / 16;
v = 9 mph ;
18 = 9 * x ;
x = 18 / 9 ;
x = 2 hours ;
The answer is 2 hours ;
Answer:$39
Step-by-step explanation:
The discounted price is going to be 60% of the original price because 100 - 40 = 60. So we want to find 60% of the original price, or 65. 65 x . 6 = 39, so the pair of rollerskates will be $39 at the discounted price.

Answer D
I can’t help but you did just help me get an answer correct
Answer:
Answer: A
Step-by-step explanation:
From the table given, the data sets are such that set A is a linear function while data set B is follows an exponential function. Given that the range of data set A over the same domain is smaller that the range of data set B over the same domain. Hence we conclude that the set A is linear and the values increase at a slower rate than set B.
