This gives you:

Can someone please help, I will give brainiest. If possible explain please.
lesantik [10]

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

or

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°

HELP PLZZ
valentina_108 [34]
Y = 11.5x + 22
y = -13x + 218

when will their balance be the same.....ur basically just subbing in 1 y for the other and u get :
11.5x + 22 = -13x + 218....now we solve for x
11.5x + 13x = 218 - 22
24.5x = 196
x = 196 / 24.5
x = 8 <== they will be the same at 8 weeks

11.5(8) + 22 = 114
-13(8) + 218 = 114
and they will both have $ 114 at 8 weeks <===
