    The wage bill for six women and five men is \$670. The bill for eight men and three women is \$610. Find the wages of (1) a man and (b) a woman. i set it up like this : 6x+5y=670 3x+8y=610 did i set it up right because word questions confuses me .

    Re: HELp with simultaneous equations in word form okay so for the first question would it be lined up like 5x-6y=3 x-4y=5 and then i solve as a simultaneous equation?

    Two numbers are such that 5 times the first is three more than 6 times more than the second. Four times the second is five more than the first. Find the numbers. and also The sum of two nubers is 90. If 20 is added to 3 times the smaller number, the result exceeds twice the larger by 50. Find...

    is this correct? 1.) 32 2/5(32 1/5) ^2=(5 SQUARE ROOT 32)2 =5(SQUAREROOT 2X2X2X2X2)2 =(5 SQUARE ROOT )2 =5 SQUARE ROOT 2 X 5 SQUARE ROOT 2 =25 (2 SQUARE ROOT 2) =50 SQUARE ROOT 2
