Answer:

x = 12

Step-by-step explanation:

The exterior angles of any polygon always add up to 360, so:

5x+4+4x+9+7x+4+9x-6+4x+1=360\\29x+12=360\\29x = 348\\x = 12

Solve for y<br> a. 4x + 5y = 25
AfilCa [17]

Answer:

y = -4/5x + 5

Step-by-step explanation:

In order to solve for y, we need to isolate the variable. First, let's subtract 4x on each side. After doing said step, we should now have this equation:

5y = -4x + 25

Next, we need to divide 5 on each side, giving us this new equation:

y = -4/5x + 5

There you go! Let me know if I did anything wrong ^-^

Use the distributive property to solve the equation 28-(3x+4)=2(x+6)+x. Show your work.
Gre4nikov [31]

Answer:

x=2

Step-by-step explanation:

28−(3x+4)=2(x+6)+x

We need to use the distributive property for the right side.

28−3x−4=(2)(x)+(2)(6)+x)

28−3x−4=2x+2+x

−3x+24=3x+12

From here we need to subtract 3x from both side.

−3x+24−3x=3x+12−3x

6x+24=12

Transfer +24 on the right side.

6x=12−24

6x=−12

Finally, divide both sides by −6

6x/-6 = -12/-6

x=2
