Answer:
You stopped at 2y-4=12
If we add same number to both sides the equation will remain true. For example if we have 5=5, and we add 7 to both sides, we get 12=12 which is also true. Now let's do this with our equation. Add 4 to both sides(to have only y on the left side). We get 2y=16, hence y=8.
Answer. 2y=16
A^2-5a = 6
a^2-5a-6 = 0
Discriminant = (-5)^2-4(1)(-6) = 49
Discriminant is positive so there are two solutions
Answer:
Substitute n =1, 2, 3, 4, 5 to get the first five terms.
Step-by-step explanation:
(4). 
To find the first term, substitute n = 1.
Therefore, 
= 2
= 6
= 18
= 54
= 168
Therefore the first five terms of the sequence are: 2, 6, 18, 54, 168.
(5). 
= 4
Therefore the first five terms in the sequence are: 6, 4, 8/3, 16/9, 32/27.
Answer:
i will answer -- justv please clarify ur question
ig its 8.7 tho ?
Step-by-step explanation:
The total would be 180 degrees because angles on a straight line would always add up to 180.
(3x+31)+(2x-6)=180
5x+25=180
-25 -25
5x=155
/5 /5
x=31
