Can someone please help, I will give brainiest. If possible explain please.

Step-by-step explanation:

The angles (8x + 28) and (4x - 7) are supplementary to each other so we can write

$(8x + 28) + (4x - 7) = 180 \Rightarrow 12x + 21 = 180$

$x = 13.25$

Also, note that the angle (4x - 7) and $\angle{TQS}$ are vertical angles, which means that they are equal to each other. Therefore,

$\angle{TQS} = 4x - 7 = 4(13.25) - 7 = 46°$

Compare the fraction 3/5 to 1/2 and then compare 2/6 to 1/2 .use symbols in your answer.

Feliz [49]

3/5 > 1/2 ~ because 3/5 is 60% of 1 and 1/2 is 50% of 1
2/6<1/2 ~ because 2/6 is 33% of 1 and 1/2 is 50% of 1

Hope I helped!

Answer:

-4x + y + 6z

Step-by-step explanation:

Combine like terms (Terms with the same variable):

(2x + 5y - z) + (-6x - 4y + 7z)

Add straight across:

2x - 6x = -4x

5y - 4y = y

-z + 7z = 7z - z = 6z

-4x + y + 6z is your answer.
