Elliot spent 3/7 of his money on some comics. He spent 1/4 of the remaining money on a pack of cards.
a) What fraction of Elliot's money has he left?
b) If he has $6 left, how much money did Elliot have at first?

a) 3/7

b) $14

Step-by-step explanation:

let the total of his Money be x

on some comics = 3/7 of x

remaining money = x - 3x/7

on a pack of cards = 1/4 of 4x/7

a) left fraction = total money - all spent money

note that; all spent money = money spent on some comics and pack of cards

left fraction = 3/7 of the money

b) left money = 3x/7

but since left money is $6

therefore, $6 = 3x/7

multiply both sides by 7

42= 3x

divide both sides by 3

x = 42/3

x = 14

total money = $14

109 is the nearest whole number/final answer! : )

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
