There is 3600 seconds per hour.
 Multiply the speed per second by 3600 to get the speed in miles per hour then convert to kilometer/hour.

4.9 * 3600 = 17,640 miles per hour

17,640 x 1.6 = 28,224 kilometers per hour

If six times a number is decreased by fourteen, the result is 124. What is the number
denis23 [38]

Answer:

\large\boxed{23}

Step-by-step explanation:

Six times a number is decreased by fourteen, the result is 124.

Write an equation that represents this

(6 * x) - 14 = 124

Multiply 6 by x to remove the parenthesis

6x - 14 = 124

Add 14 to both sides of the equation

6x = 138

Divide both sides of the equation by 6

x = 23

The unknown number is \large\boxed{23}

Hope this helps :)

Okay. fist off don't think of them as 5 units each, but 1. so if you were to put it on graphing paper and box squares each time. you would be able to get 8 in for both sides to make a square. Area then would be 1600ft squared because 8 ×5 is 40 and 40×40 is 1600. then you calculate how many squares you used. 8×8=64. and 80-64=16 so 16 pieces are left over. then 9×9 (increasing the square) is 81. so 17 pieces to increase it.
