2x + 3y = 40

-2x + 2y = 20

------------------------add

5y = 60

y = 12

-2x + 2y = 20

-2x +2(12) = 20

-2x + 24 = 20

-2x = -4

x = 2

answer is A. x = 2, y = 12

Hello!! Actually I got A x = 2, y = 12.

Whenever you plug them in, 2(2) + 3(12) = 40

-2(2) + 2(12) = 20

It worked for me this way, I hope this is the right answer. Have a great day!

3x + 6y= 180<br>What is x and y​
Diano4ka-milaya [45]

Answer and explanation:

<h2>X</h2>

3x + 6y = 180  <em>Use the original expression to find x</em>

3x = 180 - 6y  <em>Subtract 6y by both sides</em>

\frac{3x}{3} = \frac{180}{3} - \frac{6y}{3}  <em>Divide by 3 to get x</em>

x = 60 - 3y

<h2>Y</h2>

x = 60 - 3y  <em>Use the new expression to find y</em>

x - 60 = - 3y  <em>Subtract 60 by both sides</em>

\frac{x - 60}{-3} = \frac{-3y}{-3}  <em>Divide by -3 to get y</em>

-\frac{x}{3} + 20 = y

Answer:

CAB = 30.71   BCA = 90    ABC = 59.29

Step-by-step explanation:

BCA = 90

9x + 6 + 5x = 90

14 x = 90-6 = 84

x = 43/7

(43/7 ) * 5 = 30.71

90 - 30.71 = 59.29

Eleven members of the Middle School Math Club each paid the same amount for a guest speaker to talk about problem solving at the
tiny-mole [99]
The missing digit is number 3. The total amount should be $132

I multiplied 11 by the numbers 10 and above to get the possible three digit answer who has 1 as the first digit and 2 as the last digit.

11 x 10 = 110
11 x 11 = 121
11 x 12 = 132

The 11 members of the Middle School Math club each paid $12 for a guest speaker.

Please answer the following essay question:
dalvyx [7]

The land that would be settled on would have already been the Indians land. Just like in modern times, when you trespass on somebodys own property you would make them mad. This would also potentially decrease their hunting territory, further upsetting the Indians. (this isn't 5 sentences but its a start! Good luck :)
