    Simultaneous equations in word form (2)

    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 .

    Simultaneous equations in word form

    4y = x + 5 but if i bring 4y over to the equal sign it becomes x-4y and 5 is already behind the sign. so how would it become -5 :confused:

    Simultaneous equations in word form

    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?

    Simultaneous equations in word form

    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...

    Simplification of Powers of Five

    write in the form 5^r, where r is a rational number. 1.)1 2.)1/5 3)(square root 5)^7 4.)3 suare root 25 5.)square root 125 6.)1/ square roor 5 1. r = 0 (anything to the 0th power is 1) 2. y = 5^x 1/5 = 5^x x = -1 3. sqrt(5)^7 = 5^x x = 7/2 4. cube root (25) = 5^x...

    Calculating (125 2/3)^2: 3-Square-Root-of-5

    1) 125 2/3(125 1/3)^2 =( 3 square root 125)^2 =(3 square root 5x5x5)^2 =(3 square root 5 )^2 right so far?

    Solving Exponents: Simplifying Radical Expressions

    how do i know when the answer should be in square root form like 16 square root 2 or when it is suppose to be in powers like my answer for 32 2/5 when the answer was 2^2.

    How can you simplify exponents involving fractions and roots?

    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
