Answer:

The sum of a° and b° will be 180°.

Step-by-step explanation:

We know that two angles are supplementary when they add up to 180 degrees.

We also know that we know that a straight angle is said to be having 180 degrees. A straight angle does change the direction to point the opposite way.

i.e.

Straight angle = 180°

For example, a flat surface does have an angle of 180 degrees. Also, a straight stick does have a straight angle or 180 degree.

So, from the figure, the sum of a° and b° will be 180° as they add up to 180 degrees on a straight line and hence a° and b° are supplementary angles.

Therefore, the sum of a° and b° will be 180°.

Solve the equation: 10 = -4 + x
Sonja [21]
10= -4 + x    x=14 because you do the opposite of the sign you see in this case its a plus sign so you subtract -4 from ten and since the 4 is a negative and your subtracting you would add 4 I know this probably didn't help it sounds really confusing but I have hope that it did :)

X + one over two(6x − 4) = 6
Maurinko [17]

The given equation is:

x+\frac{1}{2} (6x-4)=6.

Multiplying both sides by 2 we have:

2x + 6x − 4 = 12 [ multiplication property of equality]

Combining like terms:

8x-4=12

Adding 4 both sides

8x=16.[Addition property of equality]

Dividing both sides by 8:

x=2 [Division property of equality.]

The correct option in which the equation is solved are : B. Multiplication property of equality. 2. Combine like terms. 3. Addition property of equality. 4. Division property of equality.
