Answer:

The LCM will be: 10x^3y^3

and The Solution will be: \frac{12y^2-5x}{10x^3y^3}

Step-by-step explanation:

We need to solve the problem

\frac{6}{5x^3y}-\frac{1}{2x^2y^3}

Since there is minus sign, so we take LCM of 5x^3y and 2x^2y^3

The LCM will be: 10x^3y^3

Our equation will become after taking LCM

=\frac{12y^2}{10x^3y^3}-\frac{5x}{10x^3y^3}\\=\frac{12y^2-5x}{10x^3y^3}

What is the score range for the smallest percent of students
andre [41]
<h2>Answer:</h2>

The score range for the smallest percent of students is:

                         400 to 700

<h2>Step-by-step explanation:</h2>

From the pie chart or circle graph that is provided to us the smallest percent of the students are 10%

( Since 10%  is smallest among 14%,42%,34% and 10%)

and we may observe that the smallest region is denoted  or represented by the dark blue region and the range of the score of blue region that is given to us is:

                  400 to 700

   Hence, the answer is:

                   400 to 700

lara [203]

Answer:

<h2>Length = 14</h2><h2>Width =7</h2>

Step-by-step explanation:

Let \:the\:length\:be \:x\\Perimeter = 42 cm\\Width = x -7\\\\P = 2(l+b)\\\\42 = 2(x+(x-7))\\\\42 = 2(x +x-7)\\42 = 2(2x-7)\\42 = 4x -14\\Collect\:like\:terms\\\\42+14=4x\\56 = 4x\\\\Divide \:both\:sides\:of\:the\:equation\:by \:4\\\frac{56}{4} = \frac{4x}{4} \\\\14 =x\\Length = 14\\Width = x-7\\Width = 14-7\\\\Width = 7
