Elena L [17]3 years ago

4x + 6 < -6

subtract 6 from each side

4x < -12

divide by 4

x < -3


- 2/5 x-9 < 9/10

multiply each side by 10 to get rid of the fractions

10*(- 2/5 x-9) < 10*9/10

distribute

-4x -90 <9

add 90 to each  side

-4x < 99

divide by -4 (which flips the inequality)

x> -99/4

x> -24 3/4

<h2>1:</h2>
  • 100 ounces = 6.25 pints
  • A mile unit is equal to 1760 yards.                                                      inches =mile  * 63360                                                                                              2*63360=126720

       2 Miles = 126720 Inches

  • There are 36 inches in a yard

       3600/36= 100

       3600 inches = 100 yards

  • 1 m = 1/1000 km

       6800/1000 = 6.8

       6800 m = 6.8 km

  • 1 m = 100 cm

        15000/100=150

         15000 cm=150 m

a) Johnson ran  yard in second= 9

     1 minute = 60 second

    Johnson ran yard in one minute=  9 *60= 540 yards

b) Johnson ran  yard in second= 9

     1 hour = 60 minutes *60 second= 1200 seconds

    Johnson ran yard in one hour=  9 *1200= 10,800 yards

c) Johnson ran yard in one hour=  9 *1200= 10,800 yards

   1 mile = 1760 yards

   miles did he run in one hour= 10,800 / 1760 =6

   Johnson ran 6 mile in one hour
