Answer:
Im pretty sure that you just have to find the value of X and Y...
R=rate of boat in still water
c=rate of current
d=rt
since you're given that the time it takes to travel the same distance downstream and upstream, your equation will be d_1=d_2, or rt=rt
the rate upstream is r-c and the rate downstream is r+c (because the boat's and river's rates add up)
since you know t_1 and t_1 are 5 and 3, you can now set up 2 equations
<u>5*(r-c)=45</u> because (time upstream)*(rate upstream)=distance=45 miles
r-c=45/5=9
<u>3*(r+c)=45</u>
r+c=45/3=15
r-c=9 and r+c=15, so r=12 mi/h and c=3 mi/h

Answer:
$0.25r + $5 = $12.50
Step-by-step explanation:
r represents the amount of rides Lacy went on during the day. If you do the problem in the correct order, you will get the answer
Step 1)
Subtract 5 from both sides
$0.25r + 5 (-5) = 12.50 (-5)
Step 2)
Divide by 0.25
0.25r (Divided by 0.25) = 7.50 (Divided by 0.25)
Step 3)
Answer
r = 30 rides
The value of z is zero
Step-by-step explanation:
The slope is the steepness of the line.
The formula for slope is given by:
Here
(x1,y1) = (1,z)
(x2,y2) = (2,8)
So,
The value of z is zero
