B.90 if angles are supplementary that means they add up to 180 degrees and 90 plus 90 is 180

Answer:

B. 90

Step-by-step explanation:

Since the two angles are supplementary, this means they both are on a flat line (180 degrees)

Since both A and B add up to 180, we take that number and subtract A (90) to get our answer: 90 degrees

Whats the answer for 6n+7-2n-14=5n-1​
12345 [234]

Answer:

Simplifying

6n + 7 + -2n + -14 = 5n + 1

Reorder the terms:

7 + -14 + 6n + -2n = 5n + 1

Combine like terms: 7 + -14 = -7

-7 + 6n + -2n = 5n + 1

Combine like terms: 6n + -2n = 4n

-7 + 4n = 5n + 1

Reorder the terms:

-7 + 4n = 1 + 5n

Solving

-7 + 4n = 1 + 5n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-5n' to each side of the equation.

-7 + 4n + -5n = 1 + 5n + -5n

Combine like terms: 4n + -5n = -1n

-7 + -1n = 1 + 5n + -5n

Combine like terms: 5n + -5n = 0

-7 + -1n = 1 + 0

-7 + -1n = 1

Add '7' to each side of the equation.

-7 + 7 + -1n = 1 + 7

Combine like terms: -7 + 7 = 0

0 + -1n = 1 + 7

-1n = 1 + 7

Combine like terms: 1 + 7 = 8

-1n = 8

Divide each side by '-1'.

n = -8

Simplifying

n = -8
