We can use elimination for these set of systems.
First, we need to set up our variables.
Belts=b
Hats=h
Now, the situation is 6 belts and 8 hats for $140. The situation after is 9 belts and 6 hats for $132.
Let’s set up our system of equations.
6b+8h=140
9b+6h=132
We need to eliminate a variable. Since b has coefficients of 6 and 9, we can easily eliminate b by multiplying the top equation by 3 and the bottom by -2.
18b+24h=420
-18b-12h=-264
Now let’s add.
12h=156
Let’s divide to get h by itself.
156/12=13=h
So a hat costs $13. We need to put in 13 for one of the equations so we can find the cost of a belt.
9b+6(13)=132
9b+78=132
We need b by itself.
9b=54
54/9=6
Belts are $6
We can also use the first equation to check our answers.
6(6)+8(13)
36+104
140.
So, the price of a belt is $6 while the price of a hat is $13.

State the type of angles and solve for the given variable.
Evgen [1.6K]

Step-by-step explanation:

<em>the </em><em>giv</em><em>e</em><em>n </em><em>pair </em><em>is </em><em>Alternate</em><em> Exterior</em><em> Angle</em>

<em>so </em><em>their </em><em>values </em><em>are </em><em>equal </em><em>so,</em>

<em>→</em><em> </em><em>2</em><em>x</em><em> </em><em>+</em><em> </em><em>2</em><em>6</em><em> </em><em>=</em><em> </em><em>3</em><em>x</em><em> </em><em>-</em><em> </em><em>3</em><em>3</em>

<em>→</em><em> </em><em>2</em><em>x</em><em> </em><em>-</em><em> </em><em>3</em><em>x</em><em> </em><em>=</em><em> </em><em>-</em><em>3</em><em>3</em><em> </em><em>-</em><em> </em><em>2</em><em>6</em>

<em>→</em><em> </em><em>x </em><em>=</em><em> </em><em>5</em><em>9</em>

<em>therefore</em><em> </em><em>option</em><em> </em><em>C </em><em>is </em><em>correct</em>

<em><u>hope </u></em><em><u>this </u></em><em><u>answer </u></em><em><u>helps </u></em><em><u>you </u></em><em><u>dear.</u></em><em><u>.</u></em><em><u>.</u></em><em><u>take </u></em><em><u>care </u></em><em><u>and </u></em><em><u>may </u></em><em><u>u </u></em><em><u>have </u></em><em><u>a </u></em><em><u>great </u></em><em><u>day </u></em><em><u>ahead</u></em><em><u>!</u></em>
