5. Abdullah bought 3 books and 2 pencils for Rp11.500. Maryam bought 4 books and 3 pencils for Rp16.000. If you want to buy (the same) 2 book and a pencil, it cost…. * A. Rp 4.500 B. Rp 6.500 C. Rp 7.000 D. Rp 7.500
Misalkan :
Buku = x
Pencil = y
Persamaan1
3x + 2y = 11.500
Persamaan2
4x + 3y = 16.000
EliminasiPersamaan1dan2
3x + 2y = 11.500 | × 3 |
4x + 3y = 16.000 | × 2 |
9x + 6y = 34.500
8x + 6y = 32.000
______________ -
x = 2.500
SubstitusiNilaiykePersamaan1
3x + 2y = 11.500
3 ( 2.500 ) + 2y = 11.500
7.500 + 2y = 11.500
2y = 4.000
y = 2.000
Nilai2x+y
= 2 ( 2.500 ) + 2.000
= 5.000 + 2.000

6.500 (B)
Penjelasan dengan langkah-langkah:
3b + 2p = 11.500 | ×3 | 9b + 6p = 34.500
4b + 3p = 16.000 | ×2 | 8b + 6p = 32.000
b = 2.500
3b + 2p = 11.500
3 × 2.500 + 2p = 11.500
7.500 + 2p = 11.500
2p = 11.500 - 7.500
2p = 3.000
p = 3.000/2
p = 1.500
2b + p

Jawab:
Penjelasan dengan langkah-langkah:
E : K = 3 : 4
E = 225.000
K = 4/3 x 225.000
K = 300.000
atau
E : K = 3 : 4
225.000 : K = 3 : 4
225.000 : K = ( 3 x 75.000 ) : ( 4 x 75.000)
225.000 : K = 225.000 : 300.000
maka K = 300.000

13. Ethan and daniel have some marbles. if ethan gives daniel 16 marbles, both of them will have an equal amount of marbles. if daniel gives ethan 9 marbles, the ratio of number ethan has to the number of marbles daniel has will be 6 : 1 how much do the two boys have altogether
Jawaban:
E= D + 16----> D = E-16
(E + 9) : D = 6 : 1
(E + 9) : (E-16) = 6 : 1
(E + 9) = 6 (E-16)
E + 9 = 6E - 96
E - 6E = -96-9
-5E = -115
E = 23
D = E-16 = 23-16 = 7
The amount of Ethan and Daniel's marbles
= E + D
= 23 + 7
= 20 marbles

19. There were some pencils in boxes A,B and C.Box A contained ¾ of the total number of pencils in Boxes B and C.The ratio of the number of pencils in Boxes A and C is 2:7.There were 315 more pencils in Box A than Box C.Find the total number of pencils in all the boxes.
Box A = [tex] \frac{3}{4} [/tex] of total box B and C
Ratio pencils in A and C is 2 : 7
Box A have 315 pencils than Box C
subtract the ratio 7 - 2 = 5
if box A have more pencils
[tex] \frac{7}{5} [/tex] × 315 = 441 pencils
B+C = 441 ÷ [tex] \frac{3}{4} [/tex] = 441 × [tex] \frac{4}{3} [/tex] = 588 pencils
A + (B+C) = 441 + 588 = 1.029 pencils
