Step-by-step explanation:

-8+(-9) = -17  <--- Negative    If they are both negative, then you do the simple math part and then add the negative sign

7+(-3) = 4  <---- Positive    If there are only one negative, then you get rid of the '+' and then the equation turns into 7-3. You would do the simple math.

5+(-12) = -7 <----- Negative.    Here, there is only one negative sign but the negative number is greater than the positive number. So, you would do the math 5-12 and use the negative sign.

-12+5 = -7 <----- Negative   Look at the one above this.

Answer:

96 square tiles are needed

Step-by-step explanation:

To calculate this, the first thing we need to do is calculate the total area covered by the rectangular wall.

Mathematically, the area of the rectangle = 16 * 24 = 384 ft^2

The next thing we need to do is calculate the area of the square tiles = L^2 = 2^2 = 4 ft^2

the number of square tiles needed = Area of rectangular wall/Area of square tiles = 384/4 = 96

The Ruiz family is exchanging euros for US dollars the exchange rate is 1 euro equals 1,35261 USD since the Ruiz family knows th
Tom [10]
You have to multiply the number of dollars times the conversion ratio is used in this way.

If you use the nearest hundredth approximation of the conversion ratio you have to use 1.35 instead the real exchange ratio of 1.35261

So, if they change Eu 1 will receive $ 1.35 instead of $ 1.35261.

If they change Eu 10 will receive 10 × 1.35 = $ 13.5, instead of $13.5261

If they change Eu 100 will receive 100 × 1.35 = $ 135, instead of $135.5261

If they change Eu 1,000 will receive 1000 × 1.35 = $ 1350, instead of $ 1352.61

So, you see the lose is $ 2.61 per every 1000 Euros they change.
