Answer:
<h2>The answer is option A</h2>
Step-by-step explanation:
<h3>
</h3>
<u>First of all cross multiply</u>
That's
g( wd + f ) = a + bc
<u>Multiply the terms at the left side of the equation</u>
We have
gwd + fg = a + bc
<u>Send fg to the right side of the equation</u>
That's
gwd = a + bc - fg
<u>Divide both sides by dg to make W stand alone</u>
<h3>
</h3>

<h2>
Mishka's speed = 14 km/hr</h2><h2>
Current speed = 2 km/hr</h2>
Step-by-step explanation:
Let the speed of rowing be r and speed of current be c.
If he rows with the current, Mishka rows 48 km in 3 hours.
Relative speed = r + c
Distance = 48 km
Time = 3 hours
48 = 3 x ( r+c)
r + c = 16 ---------------------------eqn 1
If he rows against the current, it takes 4 hours to travel the same distance.
Relative speed = r - c
Distance = 48 km
Time = 4 hours
48 = 4 x ( r - c)
r - c = 12 ---------------------------eqn 2
eqn 1 + eqn 2
2r = 28
r = 14 km/hr
Substituting in eqn 1
14 + c = 16
c = 2 km/hr
Mishka's speed = 14 km/hr
Current speed = 2 km/hr
Answer: X^4 you just subtract or add with exponents
Step-by-step explanation:
You would need to multiply the monthly cost, $14, by the number of months and then that would be added to the cost to join, $25
For 6 months it would cost 14 x 6 = 84 + 25 = $109
The answer would be C.
