Question

yang bagian A x B + 2C tolong jawab

Answer 1

Jawaban:

Diketahui:

• B + B + B = 15
• B + B - 2A = 4
• 5 + A + C = 16

Ditanya:

• A × B + 2C = ... ?

Jawab:

B + B + B = 15

3B = 15

B = 15 / 3

B = 5

B + B - 2A = 4

5 + 5 - 2A = 4

-2A = 4 - 10

-2A = -6

A = 3

5 + A + C = 16

5 + 3 + C = 16

C = 16 - 8

C = 8

MAKA, NILAI A × B + 2C

= 3 × 5 + 2(8)

= 15 + 16

= 31

Kesimpulan

• Nilai A × B + 2C adalah 31

Answer 2

Jawaban:

diketahui :

*B +B +B =15

3B =15

B = 5

* B+B-2A = 4

5+5-2A =4

10 - 2A =4

2A = 6

A =3

* 5+A+C =16

5 +3+C = 16

8+C =16

c = 8

A x B +2c =

3 x5 +2(8)

15 +16

= 31
