Answer:

14 flashes.

Step-by-step explanation:

1 minute = 60 seconds

x minutes = 45 seconds.

1/x = 60/45                           Cross multiply

60x = 45                               Divide by 60

x = 45/60

x = .75

10 1/2 minutes = 10.5 minutes.

x flashes / 10.5 minutes = 1 flash / 0.75 minutes   Multiply by 10.5

x = 10.5/0.75

x = 14

Minchanka [31]

Answer:

  • x+5 = -28
  • x = -33

Step-by-step explanation:

The translation to a math expression is ...

  <em>The sum of a number and 5 is negative 28.</em>

                          x     +      5      =    -28

Subtract 5 from both sides of the equation:

  x + 5 - 5 = -28 -5

  x = -33

The number is negative 33.
