Practice Skills_ Simplifying Inequality1. 3( 1/2 - y) = 3/5 + 15y. What isthe solution to the given inequality?

Angelina_Jolie [31]

3( 1/2 - y) = 3/5 + 15y

Applying distributive property:

3*1/2 - 3y = 3/5 + 15y

3/2 - 3y = 3/5 + 15y

3/5 is adding on the right, then it will subtract on the left

3y is adding on the left, then it will subtract on the right

3/2 - 3/5 = 15y + 3y

15/10 - 6/10 = 18y

9/10 = 18y

18 is multiplying on the right, then it will divide on the left

9/10*1/18 = y

1/10*1/2 = y

1/20 = y

A kite is a quadrilateral with two pairs of adjacent, congruent sides. The vertex angles are those angles in between the pairs o

umka21 [38]

Let the kite is the quadrilateral A B C D with the two pairs of adjacent congruent sides. (Please find the attached diagram also)

Now, its given in question, see from figure,

AB is congruent to AD

BC is congruent to DC

So, let us join the points A & C to form AC ; and points B and D to form BD.

So, AC is common side to triangles ABC and ADC.

So, Because AB ≈AD

BC ≈ DC

And, AC is common, therefore,

triangle ABC is congruent to triangle ADC

⇒∠ ABC ≈ ∠ADC

The above are the angle.
