$p(y)=\dfrac{3y-7}{y-A}\\\\p(3)=-2=\dfrac{3(3)-7}{3-A}=\dfrac{2}{3-A}\\\\3-A=\dfrac{2}{-2}\\\\3-(-1)=A=4$

The value of A is 4.

Answer:

The Associative property does not hold for the division of whole numbers.

Step-by-step explanation:

If ‘a’, ‘b’, and ‘c’ are the three whole numbers then, a ÷ (b ÷ c) ≠ (a ÷ b) ÷ c ⇒ 100 ÷ (25 ÷ 5) = 20 ≠ (100 ÷ 25) ÷ 5 = 4 ÷ 5. Easy Way to Remember the Properties of Whole Numbers

When you play darts, you know three darts at the board and add the scores. Bristoe and Clancy are practising. Here are the score

Alja [10]

The person who has a better average will be Clancy.

The person who has more varied scores is Bristoe.

<h3>How to calculate the average??</h3>

Bristoe - 18,32,26,53,5,29,41,15,85,9,44,28,100,37,55. The average will be the addition of the numbers as dividing by 15. This will be:

= 577/15

= 38.47

Clancy - 41,26,33,51, 26,29,60,45,60,19,42,36.

Average= 468/12

= 39

The person who has a better average will be Clancy.

The person who has more varied scores is Bristoe.

Geometry proofs <br> Need help!!

Andrew [12]

Angles ∠MOK and ∠NOL are identical by opposite angle theorem.

∠M = ∠N through given information

∠MKO and ∠NLO are congruent. Since the other two angles of each triangle are equivalent, the last angle must be equivalent to the last angle of the other triangle. (180 - ∠1 -∠2 = ∠3); you could also prove ∠MKO = ∠NLO by stating that the opposite sides of the two angles are congruent.

ΔMKO and ΔNLO by Angle-Angle-Side theorem

since ΔMKO and ΔNLO, all corresponding parts of both triangles are congruent, so therefore MO ≅ NO
