Alex made an eyeglass case and sold it for $12.00. He spent $1.29 on felt and $2.75 on a needle and thread. What was his profit?

madreJ [45]

D because 1.29 plus 2.75 is 4.04(the money that he used to make the case) and subtract that with $12 and you get $7.96 as the profit.

Please explain step by step for 0.67÷0.3=?

pentagon [3]

Multiply each of the numbers by a ten to a power that they both become whole numbers.

0.67 * $10^2$ = 67
0.3 * $10^2$ = 30

Divide as usual.

67 / 30 = 2 $\frac{1}{3}$

So, the answer is 2 1/3.

$\frac{16+x}{x^3}+\frac{7-4x}{x^3}=\frac{16+x+7-4x}{x^3}=\frac{23-3x}{x^3}\\\\======================================\\\\\frac{5}{t-1}+\frac{3}{t}=\frac{5t}{t(t-1)}+\frac{3(t-1)}{t(t-1)}=\frac{5t+3t-3}{t^2-t}=\frac{8t-3}{t^2-t}$
