Answer: y2/4 - x2/5
Step-by-step explanation:
Carlos did not use order of operations. The order of operations goes first you do <span>Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. First you do the parentheses which is 2 x 6 so now your equation is 20 - 12 + 8 / 4. Since you don't have any exponents nor multiplication left you move onto divison which is 8 / 4. Know your equation is 20 - 12 + 2. You do addtion which is 12 + 2. Then you do subtraction 20 - 14 which equals 6.
Hope this helps :)</span>
Answer:
Step-by-step explanation:
You start off by rewriting the equation:

Then you have to factor:

Then you subtract the 0.2x:

Add the positives on the right:

Add 14:

Divide:

You get x is approximately equal to 10.84
$408.04 this is so simple all you had to do was divide 2,727 by 27 then multiply that by $4.04 and you would get the answer.
