Answer: The correct option is, (B) Addition property

Step-by-step explanation:

  • Addition property : In this property, whatever is added to one side of the equal sign must be added to the other side.

        For example : If x = y then x + z = y + z

  • Multiplication property : In this property, whatever is multiplied to one side of the equal sign must be multiplied to the other side.

        For example : If x = y then x × z = y × z

  • Transitive property : If one value (x) is equal to the another value (y), which is equal to the another value (z), then the first value (x) is equal to the third value (z).

        For example : If x = y and y = z then x = z

The given inequality expression is,

5x - 9 < 91

5x -9 + 9 < 91 + 9

(Using Addition property because we are adding 9 on both the side)

5x < 100

5x ÷ 5 < 100 ÷ 5

(Using Division property because we are dividing by 5 on both the side)

x < 20

Therefore, addition property is used in the second step of solving the inequality.

5x - 9 < 91 --- given
5x - 9 + 9 < 91 + 9
5x < 100 --- addition property....because I added 9 to each side
x < 100* 1/5 --- multiplication property
x < 20

so, step 2, we used the addition property

Based on given information for each of the following, which lines cannot be parallel? a m∠2=127°, m∠3=63°\ PLZZSZZZ help :&gt;
tia_tia [17]

Answer:

Lines m and n cannot be parallel

Step-by-step explanation:

1. Because angles 2 and 3 are Same Side Interior Angles, they must be supplementary.

2. To check this you add the angles together (127 + 63) and it sums to 190 degrees, not 180

3. Since they don't agree with the laws of parallel lines, the lines that the angles are on can't be parallel

4. Angles 2 and 3 reside on lines m and n so lines m and n cannot be parallel

Please help!!!! ASAP!!!
Nookie1986 [14]

2/4 = 3/6 is true.

First, simplify the fractions:

2/4 = 1/2

3/6 = 1/2

We see that 1/2 = 1/2, so 2/4 DOES equal 3/6.
