Nan and Santo are designing a coffee table using 4 inch tiles. Nan uses 30 tiles and Sato uses half as many how many . how many
KiRa [710]
First, you have to find half of 30. To find "half" means that you have to divide by 2. 30 divided by 2 is 15, because 15 + 15 = 30.
30 + 15 = 45
Salo and Nan used 45 total tiles.
Finally, to find out if they have enough tiles you have to divide 36 and 24 by 4. This is because that will tell you how many 4 inch tiles need to be used. So, 36/4 is 9, and 24/4 is 6.
9 tiles + 6 tiles = 15 tiles
Yes, they will have enough tiles to cover the table.

The sum of a number and fourteen is less than or equal to three times the number
Arlecino [84]
I assume we are writing the equation. The sum of a number and 14 is less than or equal to three times the number.

Let's put in a few values.
The sum of a number = x and + 14 is less than < or equal to = three times 3 * the number.

Now we have: x + 14 is < or = 3 * the number.

We can just remove the "is" and "or", because this is normal math patterns.

x + 14 <= 3 * the number. 

"The Number" is referring to the "a number" at the very beginning. So we can replace that with the same variable.

x + 14 <= 3x
