Step-by-step explanation:
It could possibly be 92 but you have to take in consideration that a triangle equals a total of 180 degrees so...(180-92) which gives you 88
Answer:
n=-7/2 I hate asking for things but can i have brainliest im trying to rank up.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
n/7−12=5n+5
1/7n+−12=5n+5
1/7n−12=5n+5
Step 2: Subtract 5n from both sides.
1/7n−12−5n=5n+5−5n
-34/7n−12=5
Step 3: Add 12 to both sides.
-34/7n−12+12=5+12
-34/7n=17
Step 4: Multiply both sides by 7/(-34).
(7/-34)*(-34/7n)=(7/34)*(17)
Answer:
b
Step-by-step explanation:
2(y-2)(y+1)
(2y-4)(y+1)
2y2 + 2y - 4y- 4
2y2-2y-4
Answer:
There is no error
Step-by-step explanation:
While it is not necessary to guess an answer, because the answer can be calculated using the properties of equality, guessing is a legitimate solution method actually taught in (some) schools these days.*
The equation is properly written, data properly filled in, and the solution properly verified. There is no error.
_____
* What doesn't seem to be taught in US schools are methods of refining an incorrect guess. These are actually well-developed, and are legitimate ways to get to a good answer.
