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...
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...
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.
