Answer:

$x \ge 4.5$

Step-by-step explanation:

The number 2x is larger than 5, so 2x - 5 is the difference between 2x and 5. This difference is at least (greater than or equal to) 4.

$2x-5 \ge 4\\\\2x \ge 9\\\\x \ge 4.5$

Two numbers are co-prime if they have no common factors (other than

Triss [41]

Answer:

See below.

Step-by-step explanation:

105/3 = 35

35/5 = 7

7/7 = 1

429/3 = 143

143/11 = 13

13/13 = 1

105 = 3 * 5 * 7

429 = 3 * 11 * 13

Not co-prime

For the other parts of the problem, do the same I did above. Find the prime factorizations of both numbers, and see if they have any prime factors in common.

Answer:

30square tiles will be used to cover the floor

Step-by-step explanation:

Given:

Number of tiles to be red = 6/10

Total number of tiles used =18

To Find:

how many square tiles will be used to cover the floor = ?

Solution:

Let the number of square tile used to cover the floor be x

Then

$x \times \frac{6}{10} =18$

$x =\frac{18}{\frac{6}{10}}$

$x = \frac{18 \times 10}{6}$

$x = \frac{180}{6}$

x = 30
