Answer:

(10a-b)/8

Step-by-step explanation:

LCM(4,8) is 8

Rewrite each fraction using common denominator = 8

5a/4 is 10a/8

10a/8 - b/8 = (10a-b)/8

He paid $5.83 to make each shirt and sold each shirt at a marked-up price.
Naddika [18.5K]

we know he made a profit of 1834 for 200 shirts, let's divide those to see how much profit per shirt

\cfrac{1834}{200}\implies \cfrac{917}{100}\implies 9.17

so he made a profit of 9.17 per shirt, now profit is surplus value, value beyond the cost, we know its cost was 5.83 per shirt, so if we take 5.83 to be 100%, how much is 9.17 off of it in percentage?

\begin{array}{ccll} amount&\%\\ \cline{1-2} 5.83&100\\ 9.17&x \end{array}\implies \cfrac{5.83}{9.17}=\cfrac{100}{x}\implies 5.83x=917 \\\\\\ x=\cfrac{917}{5.83}\implies x \approx 157.29

1/4x + 1 + 3/4c - 2/3 - 1/2x<br><br> what is it equal to??
mylen [45]

Answer: -1/4x+1/3+3/4c

Step-by-step explanation:

<h2>We can't solve it but we can simplify</h2>
  1. 1/4x+1+3/4c-2/3-1/2x, try to move the equation around. Since the operations are in the same level we can do that.
  2. 1/4x-1/2x+(1-2/3)+(3/4c), 1/4 minus 1/2 can be written as 0.25-0.50 which is -0.25 or -1/4 don't forget to add x (we can do this since there like terms)
  3. -1/4x+(1-2/3)+(3/4c), now we can convert 1 into a fraction which will become 3/3, so we can rewrite is as 3/3-2/3, which is 1/3
  4. -1/4x+1/3+3/4c, We can't simplify anymore so this is our final answer.
