Identify the number of solutions of the system of linear equations solve the system if there are in definitely many solutions write the ordered triple in terms of X if there is no solution leave each box empty x+y+z=3

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

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
