Answer:
A
Step-by-step explanation:
In pattern A, we see that each number is 3 more than the one before it. B is incorrect because the pattern is +9. C is incorrect because the numbers in Pattern A is 3x Less than the corresponding numbers in Pattern B. D is incorrect because the numbers in Pattern B are 3x more than the numbers in Pattern A.

Answer:
see explanation
Step-by-step explanation:
the ratio of the opposite interior angles = 8 : 9 = 8x : 9x
The exterior angle of a triangle = sum of the opposite interior angles, hence
8x + 9x = 119
17x = 119 ( divide both sides by 17 )
x = 7
8 parts = 8x = 8 × 7 = 56
9 parts = 9x = 9 × 7 = 63
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 angles from 180 for third angle in triangle
180° - (56 + 63)° = 180° - 119° = 61°
The 3 angles of the triangle are 56°, 61°, 63°
Answer:
I only know what y is, y is 4a, wait I think a is z and z is a. I’m not sure
Step-by-step explanation:
Answer:
The fifth term is -4
Step-by-step explanation:
The sequence has a common difference therefore, it is an arithmetic sequence
The formula for arithmetic sequence is
<em>where,</em>
<em>an is the nth term,</em>
<em>a1 is the first term,</em>
<em>n is the term number and</em>
<em>d is the common difference</em>
<u>Find the 5th term.</u>
an = a1 + ( n-1 ) d
a5 = 20 + ( 5-1 ) -6
a5 = 20+ ( -24 )
a5 = -4
