Answer 1
the answer would be x = 1
Answer 2

Answer:

x = 1

Step-by-step explanation:

1/2(8x-6) = -1/3(9x-12)   distribute

4x-3 = -3x+4                 add 3x to both sides

7x-3 = 4                        add 3 to both sides

7x = 7                            divide by 7 on both sides

x = 1

Solve the inequality 2x + 3 > 19

Answers

Answer:

x > 8

Step-by-step explanation:

Given

2x + 3 > 19 ( subtract 3 from both sides )

2x > 16 ( divide both sides by 2 )

x > 8

The solution of the inequality 2x + 3 > 19 is  x>8.

The relationship between the two values that are not equal to each other, either they are greater or less than each other, is called as inequality.

A collection of constants, variables connected using one or more arithmetic operator is called an expression

Example = 4y, 3x+4.

The inequality of the expression 2x + 3 > 19 is calculated as:

2x + 3 > 19

Subtract 3 from both the sides,

2x > 19 -3

2x > 16

Divide both side by 2, to get the inequality,

[tex]x > \dfrac{16}{2}[/tex]

Where, x> 8.

The inequality of the expression 2x + 3 > 19 is x> 8.

State if the two triangles are congruent. If they are, state how you know.
Are they
SSS OR SAS OR NOT CONGRUENT STATE HOW?

Answers

Answer:

1) SAS, 2) SAS, 3) SAS, 4) Not Congruent, 5) SSS, 6) SSS

Step-by-step explanation:

1) SAS - because the two tick marks match up, the right angle is shared, and the two triangles share one side

2) SAS - because the one tick mark matches up, the angles are shared, and the two triangles share one side

3) SAS - because the two tick marks match up, the angles are shared, and the two triangles share one side

4) Not Congruent - because the triangle on the left has the angle in between the tick marks while the triangle on the left does not have the angle in between the tick marks

5) SSS - because the two pairs of tick marks match up and the two triangles share a side

6) SSS - because the two pairs of tick marks match up and the two triangles share a side

hope that helps, good luck

It is found that the options are 1) SAS, 2) SAS, 3) SAS, 4) Not Congruent, 5) SSS, 6) SSS.

What is SAS similarity theorem?

ΔABC ~  ΔDEF  only if ratio of two sides of ΔABC and corresponding two sides of ΔDEF is equal and the angle included in both sides are congruent.

1) SAS similarity theorem proved that the two tick marks match up, the right angle is shared, and the two triangles share one side.

2) SAS similarity theorem proved that the one tick mark matches up, the angles are shared, and the two triangles share one side.

3) SAS similarity theorem proved that the two tick marks match up, the angles are shared, and the two triangles share one side.

4) Not Congruent, since the triangle on the left has the angle in between the tick marks while the triangle on the left does not have the angle in between the tick marks.

5) SSS similarity theorem proved that the two pairs of tick marks match up and the two triangles share a side.

6) SSS similarity theorem proved that the two pairs of tick marks match up and the two triangles share a side.
