Feet: (2 + 1) + (2 + 1) = 3 + (2 + 1) = 3 + 3 = 6

Inches: (7 + 5) + (7 + 5) = 12 + (7 + 5) = 12 + 12 = 24

So, 24 inches converts to 2 feet

Add Feet: 6' + 2' = 8 feet

If I write this problem plugging in the values (304/16) ^2 = c^2; and a^2 = ( 192/16^2) + b^2 = n^2, then do the rules for equations apply -- meaning what value is applies to one side of an equation if that same value is applied to the other side, then the answer remains the same? If that rule is ap...

I need a lot of practice with word problems. I can learn to turn problems around, backwards and forwards, but I need to practice this a lot. Any additional resources online for struggling students would be appreciated. Just for practice I took on this problem and couldn't come up with an equation to...

On my first pass I came up with the same 80.xx distance for B that you did. However, I realized as you that this was an error. The problem states B = 10.65 < M .... so, M is B + 6.9m or G - 6.9m. 58.95 = 69.60 #3 M - 10.65m (question states #4 B threw 10.65m < #3 M. I imagine looking at the problem ...

Question about clarification of the process -- When Adding the two equations [ ( x + y = 60 ) + ( x - y = 24 ) ] and result was 2x = 84. The reason nothing was done with the "y" variable at that point is because first 2x = 84 had to be Simplified, Solved and then plugged in value of x to e...
