108 miles 3 hours = 36 mph upstream
108 miles 2 hours = 54 mph downstream
bv = boat velocity in still water
cv = current velocity
bv -cv = 36
bv +cv = 54 Adding both equations
2*bv = 90
boat velocity in still water = 45 mph
since bv + cv = 54
then we know the current velocity = 9 mph
Answer:
1.) x=4
2.) x=14
Step-by-step explanation:
FOR #1:
1.) In order to solve the parallelogram, you must know that each opposite sides must equal...
so KL=JM and KJ=LM
2.) To solve for "x", you must substitute

so it should end up with...

3.) Solve the equation with some algebra

FOR #2:
1.) In order for a square, rectangle, parallelogram, (or any shape with four sides), it must equal to 360°. And you just have two given angles, which equal to 180, so that means the unknown equals to 180...So in this case you should have

as your equation...
2.) Solve with algebra


<u><em>multiplied</em></u>
Answer:
For number one the 3.75 oz container for $9.75 would be the better deal
For number two the answer is 6 1/4
Must show fractional dimensions!
