Well knowing these are both obtuse angles of the same shape and size we can begin. were looking to show AC is equal to DF we start by connecting A to C. A goes to C and makes this half an Oval shape  along the bottom line now try connecting A to B and C to B AB and CB are not the same as AC and since these angles are the same shape and size we know DF should do the same so now we connect D to E and F to E similar to AC they do not match nor do they match AC itself leaving us to compare D to F after we do this we see that it creates the same sized half an oval as AC showing us that they are equal. :)

Solve<br> -2x+3y=-9<br> 4x-6y=2
mr Goodwill [35]

Step-by-step explanation:

<em>Given</em><em>,</em>

<em>-2x </em><em>+</em><em> </em><em>3</em><em>y</em><em> </em><em>=</em><em> </em><em>-</em><em>9</em><em> </em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em> </em><em>(</em><em>eqⁿ</em><em> </em><em>1</em><em>)</em>

<em>4</em><em>x</em><em> </em><em>-</em><em> </em><em>6</em><em>y</em><em> </em><em>=</em><em> </em><em>2</em><em> </em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em> </em><em>(</em><em>eqⁿ</em><em> </em><em>2</em><em> </em><em>)</em>

<em>now,</em>

<em>multiply </em><em>eqⁿ</em><em> </em><em>1</em><em> </em><em>by </em><em>2</em>

<em>so </em><em>we </em><em>got</em><em>,</em>

<em>-4x </em><em>+</em><em> </em><em>6</em><em>y</em><em> </em><em>=</em><em> </em><em>-</em><em>1</em><em>8</em><em> </em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em>-</em><em> </em><em>(</em><em>eqⁿ</em><em> </em><em>3</em><em>)</em>

<em>now</em><em>,</em>

<em>subtract </em><em>eqⁿ</em><em> </em><em>2</em><em> </em><em>from </em><em>eqⁿ</em><em> </em><em>3</em>

<em>we </em><em>got,</em>

<em>-8x </em><em>=</em><em> </em><em>-</em><em>1</em><em>6</em>

<em>x </em><em>=</em><em> </em><em>-</em><em>1</em><em>6</em><em>/</em><em>-</em><em>8</em>

<em>x </em><em>=</em><em> </em><em>2</em><em>,</em>

<em>so </em><em>,</em><em> </em><em>after </em><em>putting</em><em> </em><em>values </em><em>in </em><em>the </em><em>eqⁿ</em><em> </em><em>2</em>

<em>we </em><em>got,</em>

<em>4</em><em>(</em><em>2</em><em>)</em><em> </em><em>-</em><em> </em><em>6</em><em>y</em><em> </em><em>=</em><em> </em><em>2</em>

<em>8</em><em> </em><em>-</em><em> </em><em>6</em><em>y</em><em> </em><em>=</em><em> </em><em>2</em>

<em>6</em><em>y</em><em> </em><em>=</em><em> </em><em>2</em><em> </em><em>-</em><em> </em><em>8</em><em> </em><em>=</em><em> </em><em>6</em>

<em>y </em><em>=</em><em> </em><em>6</em><em>/</em><em>6</em>

<em>y </em><em>=</em><em> </em><em>1</em>

<em>x </em><em>=</em><em> </em><em>2</em><em> </em><em>and </em><em>y </em><em>=</em><em> </em><em>1</em>

at a bargain store, Tanya bought 4 items that each cost the same amount. Tony bought 5 items that each cost the same amount, but
rjkz [21]

1. You can call x to the cost of each one of Tanya's items and y to the cost of each one of Tony's items.

2. Based on the information given in the problem and knowing that both paid the same amount of money, you can write the following expression:

5(x-1.25)=4x

3. You must solve for x:

5x-6.25=4x\\ x=6.25

4. The total amount of money that Tanya and Tony paid was:

4x=4(6.25)=25 dollars

5. Therefore, the amount of money that Tony paid for each item was:

y=\frac{25}{5} =5 dollars

The answer is:  The individual cost of each Tanya's items is 6.25 dollars and the individual cost of each Tony's items is 5 dollars.
