Question

Tolong di bantu ya ka sama penjelasan nya​

Answer 1

misal, matematika = M, biologi = B

2 M + 3 B = 300

jika nilai biologi 50 (syarat 2), maka

2M + 3x50 = 300

2M + 150 = 300

2 M = 150

M = 75

M + B = 75+50 = 125 (tdk lulus)

Jika nilai M = 70 (syarat 1)

2 x 70 + 3 B = 300

140 + 3 B = 300

3 B = 160

B = 160/3 = 53,3

M + B = 70 + 53,3 = 123,3 (tdk lulus)

Jika M + B = 130 (syarat 3)

M = 130 - B

2 M + 3 B = 300

2 ( 130-B) + 3 B = 300

260 - 2 B + 3B = 300

B = 300-260 = 40. ( tidak lulus)

A. pasti ditolak
