12x > 10(2x-3) -10 12x > 20x - 30 - 10
12x > 20x - 40
12x - 20x > -40
8x > -40
X > -5

no

Step-by-step explanation:

12x-20x=-8x

so it would be -8x>-40

and you would divide both sides by -8

and get x<5

x < 5

Step-by-step explanation:

12x > 10(2x - 3) - 10 ← distribute parenthesis and simplify right side

12x > 20x - 30 - 10

12x > 20x - 40 ( subtract 20x from both sides )

- 8x > - 40

Divide both sides by - 8, reversing the symbol as a result of dividing by a negative quantity.

x < 5

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
