Answer:

Step-by-step explanation:

To determine if x = 6 is a solution, substitute x = 6 into the left side of the equation and if equal to the right side then it is a solution.

2(6) - 5 = 12 - 5 = 7 ≠ 1

Then x = 6 is not a solution of the equation since a false statement results after replacing x with 6 (B)

PLEASE HELP !!!!!!!!!!!!!!!!!!!!!!! QUESTION ATTACHED

DIA [1.3K]

Angle-5 and angle-7 are 'vertical angles', so they're equal,
and we can write ...
 10x- 9 = 9x

Subtract 9x from each side: x - 9 = 0

Add 9 to each side: x = 9

Now that we know what 'x' is, we can find the size of Angles-5 and -7 .

Angle-7 = 9x = 81° .

Now look at Angle-6 ... the one that's the answer to the problem.

Angle-6 and -7 together make a straight line, so they must
add up to 180°.

 Angle-6 + 81° = 180°

Subtract 81° from each side: Angle-6 = 99° .
