Mathematics

7 0

Answer:

x = -13

Step-by-step explanation:

Find LCM for 5 , 10.  LCM of 5 , 10= 10

\frac{x-3}{5}-\frac{x+1}{10}= -2\\\\\frac{(x-3)*2}{5*2}-\frac{x+1}{10}=-2\\\\\\\frac{2x-6}{10}-\frac{x+1}{10}\\\\\\\frac{2x - 6 - (x+1)}{10}= -2\\\\\\\frac{2x - 6 - x -1}{10} = -2\\\\\\\frac{2x -x - 6 - 1}{10} = -2 \\\\\\\frac{x - 7}{10} = -2\\\\\

Cross multiply,

x - 7 = -2 * 10

x - 7 = -20

     x = -20 + 7

    x = -13

16 plus 5 times a number is more than the number minus 8. Write an inequality and solve it
Radda [10]

n > -6 is the inequality for 16 plus 5 times a number is more than the number minus 8

<em><u>Solution:</u></em>

Given statement is:

16 plus 5 times a number is more than the number minus 8

We have to write a inequality

From given statement,

16 plus 5 times a number is more than the number minus 8

Let the number be "n"

Therefore,

16 plus 5 times "n" is more than "n" minus 8

Here, "plus" means addition and "minus" means subtraction and "times" means multiplication

Thus the statement is translated into inequality as:

16 + 5n >n-8

Simplify the inequality

16 + 5n >n-8\\\\\mathrm{Subtract\:}16\mathrm{\:from\:both\:sides}\\\\16 + 5n -16 > n - 8 -16\\\\5n >n-24\\\\\mathrm{Subtract\:}n\mathrm{\:from\:both\:sides}\\\\5n-n>n-24-n\\\\\mathrm{Simplify}\\\\4n>-24\\\\\mathrm{Divide\:both\:sides\:by\:}4\\\\\frac{4n}{4}>\frac{-24}{4}\\\\n>-6

Thus the soultion is n > -6
