Tolong di jawab kk soalnya butuh banget

Jawaban:

7. B

8. C

9. C

10. B

11. B

Penjelasan dengan langkah-langkah:

7 :

Dik : a = -5, b = -4, c = -3

(8a + 6b) : (a + c) =

[(8 • -5) + (6 • -4)] : (-5 + -3) =

(-40 – 24) : -8 = -64 : -8 = 8

8 :

120 • (40 + 30) = (120 • 40) + (120 • p)

120 • 70 = 4800 + 120p

8400 = 4800 + 120p

120p = 8400 – 4800

120p = 3600

p = 3600 : 120

p = 30

9 :

-16 < -7

10 :

-7 < 7

11 :

Dik : a = 6

4a + 8 = 4 • 6 + 8

= 24 + 8 = 32

Semoga bermanfaat

jangan lupa jadikan jawaban terbaik yaa ^_^
