Answer:
x = 1
y = 3
Step-by-step explanation:
2x + 1 = y ------- eqn (1)
2y = 6--------eqn (2)
from eqn(2)
2y = 6
y = 3
when you divide 6 by 2y
substitute y = 3 into eqn (1)
2x + 1 = y
2x + 1 = 3
2x = 3-1
2x = 2
therefore
x = 1
Answer:
7.1, 7.3, 7.5 Any integer is a rational number.
(7.3 may be wrong, but I'm sure its not!)
The opposite angles of a cyclic quadrilateral add up to 180 degrees , so
2x + 3 + 4x + 3 = 180
6x = 180 - 6
6x = 174
x = 29
so m<C = 2(29) + 1 = 59 degrees
To solve this problem, we need to know the formula for the nth term of an arithmetic sequence. The formula is

= t₁ + (n-1)d, with

being the nth term, t₁ being the first term, and d being the distance between terms. Now we can substitute values to figure out what

is. When substituting, the equation becomes:

= 12 + 29(-6)

= -162
That means that the 30th term in this arithmetic sequence is
-162.
