the perimeter of a rectangle is 40 feet. If the length is 15 feet, 6 inches ; what is the width? How to u get 4” 6

Step-by-step explanation:

1 ft= 12 inches

we know l=15 ft and 6 inches

2L=31 inch

P=2L+2W=40ft

2W=40-2*(15ft6inches)

2W=40-31=9 inch

w=9inch/2=4 ft 6 inches

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
