Velocity Against Current = 108 / 3 = 36 km/hour
Velocity With Current = 108 / 2 = 54 km/hour

"vsw" means velocity in still water  "cs" means current speed
vsw -cs = 36
vsw +cs = 54  Adding both equations
2 * vsw = 90
velocity in still water = 45 km/hour
current speed = 9 km/hour

Deijah gave Isaiah $6.25 in nickels and quarters. If 12 coins were quarters, how many coins were nickels? Which equation models
dem82 [27]
Deijah has $6.25. 

Now, this 6.25 is comprised of 0.05s and 0.25s. 
We know that there are 12 0.25s.

We now want to know how many remaining 0.05s there are.

Again, we know that the number of 0.05s he has, which is 12, multiplied by 0.05, plus the number of 0.25s he has, multiplied by 0.25, equals 6.25.

Thus, the answer is A, 0.25 x 12 + 0.05 x n = 6.25.

Lines l, m, and n are parallel.<br><br> What is the value of x?<br><br><br> °
LUCKY_DIMON [66]
Since you know the given angle is 46deg. You also know that a straight line is equal to 180deg. So it's a supplementary angle, therefore you subtract 46 from 180 and get 134. And since the l, m, and n are parallel, they have congruent angles. So x = 134deg.
