Answer:

Each poodle requires 1 balloon(s) and each poodle requires 3 balloons.

Step-by-step explanation:

The equations that should be formed are:

3x + 3y = 12

3x + 2y = 9

In this scenario, x is the number of balloons required for a poodle, and y is the number of balloons required for a giraffe.

The question says that it should be solved using elimination.

This means that we have to completely reduce a variable to find the answer of the other remaining value. Since in both equations the coefficient of x is 3, they can cancel out when we subtract one from the other:

3x + 3y = 12

- 3x + 2y = 9

-----------------------

y = 3

This means that the number of balloons required for a giraffe is 3.

We can then put in this value of y, 3, into the equation to solve for x.

3x + 3 (3) = 12

3x + 9 = 12

3x = 12 - 9

3x = 3

x = 1

This reduces into the number of balloons required for a poodle to be 1.

We can confirm by plugging it in into the other equation.

3x + 2 (3) = 9

3x + 6 = 9

3x = 9 - 6

3x = 3

x = 1

After confirming, this should be the answer.

Hopefully this helps!

Answer:

Arranging the solutions from the least to the highest;

1. 1.743 x 10⁻²

2. 3.626 x 10⁻²

3. 4.64 x 10⁻²

4. 3.162 x 10²

5. 4.214 x 10³

Step-by-step explanation:

The solutions of the mathematical expression are calculated as follows;

$1. \ \ (4.3\times 10^6)(9.8\times 10^{-4}) = (4.3\times 9.8\times 10^{6-4}) = (42.14\times 10^2)= 4.214 \times 10^3$

$2. \ \ (2.9\times 10^7)(1.6\times 10^{-9}) = (2.9\times 1.6\times 10^{7-9}) = 4.64\times 10^{-2}$

$3. \ \ \frac{(4.7 \times 10^3)(8.6\times 10^{-7})}{(3.8\times 10^{-4})(6.1 \times 10^2)} = \frac{(4.7\times 8.6\times 10^{3-7})}{(3.8\times 6.1\times 10^{-4+2})} = \frac{4.042 \times 10^{-3}}{2.318\times 10^{-1}} = 1.743\times 10^{-2}$

$4. \ \ (4.9\times 10^3)(7.4\times 10^{-6}) = (4.9\times 7.4\times 10^{3-6}) = 3.626\times 10^{-2}$

$5. \ \ \frac{(3.9 \times 10^5)(8.7\times 10^{-3})}{(3.7\times 10^{-5})(2.9 \times 10^8)} = \frac{(3.9\times 8.7\times 10^{5-3})}{(3.7\times 2.9\times 10^{-4 +8 })} = \frac{3.393 \times 10^{-1}}{1.073\times 10^{-3}} = 3.162\times 10^{2}$
