6. 4(-8x+5)=-32x-26
-32x+20=-32x-26
this is false. 20=-26 !

7. -18-6k=6(1+3k)
-18-6k=6+18k
-6k-18k=6+18
-24k=24
k=-1

8. 8x+4(4x-3)=4(6x+4)-4
8x+16x-12=24x+16-4
8x+16x-24x=16-4+12
this is false. 0=24 !

9. 38+7k=8(k+4)
38+7k=8k+32
7k-8k=32-38
-k=-6
k=6

10. 3(1-3x)=5-(9x+2)
3-9x=5-9x-2

nevsk [136]

Answer:

c

Step-by-step explanation:

FREE BRAINLIEST!! ill also answer questions that you have posted if you answer correctly!!!! (42pts)
Elza [17]

<em>Answer:</em>

∠WVR = 156

<em>Step-by-step explanation:</em>

Angles in a triangle add up to 180

∴ ∠SRT + RST + RTS = 180

∴ ∠SRT + 109 + 47 = 180

∠SRT = 24

Alternate Angle Theorem

∠SRT = 180 - ∠WVR

24 = 180 - ∠WVR

24 - 180 = - ∠WVR

-156 = - ∠WVR

∠WVR = 156

Have a beautiful day.
