How do you solve his

Hello!

We know that the angles in a rectangle are 90°

Since they are 90° then the two separate angles add to 90

4x - 12 + x + 2 = 90

Combine like terms

5x - 10 = 90

Add 10 to both sides

5x = 100

Divide both sides by 5

x = 20

Now we put x into the two angles

x + 2 = ?

(20) + 2 = 22

4x - 12 = ?

4(20) - 12 = ?

80 - 12 = 68

The answers are
x = 20
4x - 12 = 68
x + 2 = 22

Hope this helps!

Justify each step in solving the equation -3(2x-3)=25-8x by writing a reason for each statement.
Mice21 [21]

Answer: x= 8.


Step-by-step explanation: Given equation -3(2x-3)=25-8x.

Step 1: We have -3 in front of (2x-3). We always simplify a parenthesis first.

Therefore, applying Distributive property in first step, we get

-6x +9 = 25-8x.

Step 2:  We need to get rid 9 from left side to get constant numbers on right side.

9 is being added on left side.

So, we would apply reverse operation of addition.

Therefore, applying Subtraction property of equality, we get

-6x +9-9 = 25-8x-9

-6x =16 -8x.

Step 3: We need to get rid 8x from right side.

The reverse operation of subtraction is addition.

Therefore, applying Addition property of equality, we get

-6x+8x =16 -8x+8x

2x = 16.

Step 4: We need to isolate it for x.

So, applying Division property of equality, we get

\frac{2x}{2}=\frac{16}{2}

<h3>x= 8.</h3>
