Answer:
$60
Step-by-step explanation:
Let x represent the initial money she had
She spent 3/5 of her money on a bag, That is;
3/5 of x
= 3/5 * x
and 1/6 of x on a belt
Therefore, the total money she spent is
3/5 * x + 1/6 * x
She had $14 left after all her purchases
To find how much she had left, sum up all her spending and what she has left
3/5 * x + 1/6 * x + 14 = x
collect like terms
3/5 x + 1/6 x - x = -14
23/30 x -x = -14
-7/30x = -14
x = $60
Step-by-step explanation:
ln((sin(x))^3)'
Chen Lu
= (((sin(x))^3)' / (sin(x))^3
Chen Lu
=(3sin²(x)cos(x)/ (sin(x))^3
= 3cos(x)/sin(x)
=3cot(x)
