(i)Tuliskan satu persamaan linear jika Encik Faizal membayar RM52
(i) Seterusnya, hitung bilangan pen yang di beli oleh Encik Faizal,jika dia membayar RM38 untuk belian beberapa pen dan sebuah buku
Encik Faizal bercadang membeli _x_ batang pen dengan harga RM6 sebatang dan sebuah buku berharga RM10
Jawab:
i. 6x + 10 = 52
ii. x 4 2/3
Penjelasan dengan langkah-langkah:
i. 6x + 10 = 52
6x = 42
x = 7
ii. 6x + 10 = 38
6x = 28
x = 4 2/3
Jawab:
(i) 6p + 10 = 52
(ii) the number of pens = 5
Penjelasan dengan langkah-langkah:
I'm bad at Malaysian; I'd rather speak in English because most of the Malays are indeed fluent speakers.
Given that
–> Each pen costs 6 Ringgits.
p = pen
Therefore the algebraic expression would be
6p
–> A book costs 10 Ringgits
b = book
Therefore the algebraic expression would be
b = 10
–> The total amount of money paid, is 52 Ringgits.
(i) Determine the linear equation for the aforementioned problem.
6p + b = 52
Therefore
6p + 10 = 52 <– answer
6p = 52 – 10
6p = 42
p = 42/6
p = 7
He will have to pay 52 Ringgits for 7 pens and a book
—————
(ii) Determine the number of pens if he buys a book and pays 38 Ringgits
The suitable algebraic expression for the aforementioned problem would be:
6p + 10 = 38
Solve for p (the number of pens – bought alongside the book – if he pays 38 Ringgits)
6p = 38 – 10
6p = 28
p = 28/6
p = 4,66
Rounded to the nearest unit, the number of pens = 5 <– answer
