'If a brick weighs seven pounds plus half a brick, what does a brick and a half weigh?'
But after thinking about it more, I now realise I got that wrong, LOL!I'll let someone else have their say.
Sorry anonymous, I don't accept anonymous comments.
HintA little algebra goes a long way.
A brick and a half weighs exactly the same as a brick plus half a brick.
Nick KYou must be a politician?
Okay Adolf, the mathematical answer is 10 1/2 pounds!
I agree with Bloggs.
Well done J Bloggs and Johno.
B = 7 plus B/2 > therefore B-B/2 = 7 > therefore B/2 = 7 therefor B=7 and B+B/2 = 10.5. Yes they're right but my bricks are 3.5kg and measure 22cm by 11cm by 7 cmthats [ 22*7*22 = 1694 cu cm and if that was water > 1694 grams that is 1694/453 [ where 453 is grams per pound ] = 3.74lb and 2.2 lb = approx 1kg so my bricks are about twice as heavy as water.
So, if by accident a gender identity free speech fascist liberal fell into the water with a brick around each foot,how quickly would he sink out of view, and would anyone care.
Ah yes, I misread it - 21 pounds. I passed UE maths and all.Nick K
I abstained after google algebra delivered that b plus 1/2 b equaled 14.I only reached SC maths and the rotund thespian masquerading as a Maths teacher, gleefully informed me on leaving Maths two exam (geometry and trig) in 1958, I had most probably failed.
"a brick weighs seven pounds plus half a brick" brick = 7lbs + half brickso: brick - half brick = 7lbs brick - half brick = half brickso: half brick = 7lbsthus: 3 x half brick = 3 x 7lbs brick and a half brick = 21lbs QED
jeez, knock me over
