Work backwards. 64+17 is 81. 81/3 is 27
solve in reverse 49+15=64 64/8=8 8 is the answer 8*8-15=49
I say 247. Add the number by itself and subtract 3. :]] ~Mega:]
113 + 64 = 177
From the first term subtract 19 to get the second, and continue to subtract the next smaller odd number to proceed down the line:100 (-19) 81 (-17) 64 (-15) 49 (-13) 36 (-11) 25 (-9) 16

2y - 8 = 14y + 64 Subtract 2y from both sides: -8 = 12y + 64 Subtract 64 from both sides: -72 = 12y or 12y = -72 Divide both sides by 12: y = -6

10 and 8. 10² = 100. 8² = 64. 100 - 64 = 36

You have a number of choices, including: -- Add -32 -- Subtract +32 -- Multiply by 1/2 -- Divide by 2 -- Raise 64 to the 5/6 power
