Answer:

168 seconds

I edited the answer.

Step-by-step explanation:

To find the the time taken for both lights to flash at the same time, we need to find the lowest common multiple of 28 and 24.

28 x 6 = 168, 24 x 7 = 168

The LCM of 28 and 24 is 168.

So it takes 168 seconds for both lights to flash at the same time.

Which is a solution of the inequality 5≤−4x−65≤−4x−6?
lara [203]
Step 1: Add 65 to all sides

Step 2: Add 4x to all sides

Step 3: subtract 70 to all sides

Step 4: divide by 4 to all sides

Ending: x is greater than or equal to -17.5

You will end up with it saying -17.5 is greater than or equal to -2.75 but since -17.5 is not greater than -2.75 the answer to this problem is ...

No solution because the inequality that you end up with won't make sense and therefore does not work in the problem

Answer: NO SOLUTION (yayayyayay).

The 5x5 square  grid has 6 , 2 x 2 subgrids and the least value of n for which you can be certain that it will have a 2 x 2 subgrid of grey squares is 12.

<h3>What is a Square ?</h3>

A square is a polygon with four sides and all the sides are equal and parallel and all the angle value is 90 degree.

(a) The 5x5 square  grid has 6 , 2 x 2 subgrids.

(b) the least value of n for which you can be certain that it will have a 2 x 2 subgrid of grey squares is 12

as it can be understood from the figure 2 that only the last square doesn't have a pair and the rest all does

more than that will be extra but 12 will be enough to make all the grey squares of 2 x 2 subgrid .
