Answer:
x = 34°
y = 15
Step-by-step explanation:
x + 146 = 180
x = 34°
4y + 8 + 5y + 3 + 34 = 180
9y + 45 = 180
y = 15

Explaination:
Step-by-step explanation:
B: yes; 18^2 + 29^2=1165(equal sign with slash) 23^2
Answer:
-1/3 - (-5/12) = 1/12.
Step-by-step explanation:
Simpler equation:
6/12 + (-5/12) = 1/12
Or This:
6/12 - 5/12 = 1/12.
hope this helped.
Alright, let's factor this to get the answer.
3k^2-10k+7
To find the factors, we want to think "What will add up to -10, and multiply to (+)7?"
Because the leading coefficient is 3, we know that we can take one factor of 7 and multiply it by 3.
Thus, this factors to
(3k-7)(k-1)
(if you FOIL it it should come out to be the original equation)
From this, set both of those [(3k-7) and (k-1)] equal to zero and solve
3k-7=0
3k=7
/3
k=7/3
or
k=1
