When my son come home from the school Fridai, he bring back the failing grade for test in mathematics in the pre algebre. He is senior in the high school, end he say he get strait E's and F's. He tell me E is for exelent end F is fantastik. I em disappoint in him when he bring test that say 0 on it, but I also cant solve eny of the problems. Some of problem say.
(1) If x+2y-x+3y is equal to 10 cents, what is the value of x in dollars?
(2) Mike is twice as old as Colin. In 3 years, he is still twice as old as Colin. How old is Mike?
(3) An electric train moves west at 90 mph into an east wind at 40 knots. What direction will the smoke blow?
(4) A pool is 9x30x12 feet. If 8 liters can drain per hour, at what point in time will ice be able to form in the pool given that the outside temperature is -500 degrees F?
(5) A box is twice as wide as it is high and three times its length. When creshed, how big will this box be?
Can anyone solve?

(1) x can be any amount of dollars and still make this equation true, as long as y = 2 cents or .02 dollars. So consider that chipping in my .02 dollars worth.
(2) This is impossible, unless Mike and Colin were never born and are age 0. So Mike is twice 0, or 0. And three years later, their ages are both 0 also.
(3) The smoke blows up the backside of whoever wrote these questions.
(4) At -500 degrees F, hell will have frozen over. At that point math will no longer exist. Yay!
(5) The box, if flattened to the side, will have the same width, but the height will be flattened to 0, and the length will be equal to two of the sides collapsed on each other. Although the volume will be 0, the width (being twice the height and 3 times the length) means the area is W x (1/2 W + 1/3 W). So the flattened area is 5/6 W^2 square units.
I would still sue the shipping company for damaging the box, and whoever wrote these questions for torturing your son.

If x+2y-x+3y is equal to 10 cents
x=0 dollars
y=2 cents
0+2X2-0+3X2= 10 cents

These questions are IMPOSSIBLE for me to solve and are just making my brain hurt.
When is your son ever going to use these methods in real life? Never, so they shouldn't be teaching it.
What has happened to schools?
