(4m - 1 ) /2

(4m + 1 ) /2

4m - 1 /2

4m / 2

The given expression is (4m - 1 ) /2. This expression represents the division of the quantity 4m - 1 by 2. When we divide a number by 2, we are essentially splitting it into two equal parts. In this case, we are dividing the expression 4m - 1 by 2. Therefore, the correct answer is (4m - 1 ) /2.

S(7r + 4 )

S(7r - 4 )

R(7s - 4 )

7rs - 4

The given expression can be simplified by distributing the negative sign to both terms inside the brackets. This results in -4s + 4rs. Then, we can factor out an s from both terms, giving us s(-4 + 4r). Therefore, the correct answer is s(7r - 4), not the other options provided.

10. Harga sebiji gula-gula dan coklat ialah 50 sen dan 70 sen masing - masing. Tan membeli m biji gula – gula dan 3n coklat dengan bayaran RM 15. Tulis satu ungkapan bagi baki wang Tan, dalam sen.

Baki wang = 1500 – (50m - 210n )

Baki wang = 1500 – 50m +210n

Baki wang = 1500 + (50m +210n )

Baki wang = 1500 – (50m +210n )

The given expression for the balance of money Tan has is 1500 subtracted by the sum of 50m and 210n. This means that the balance of money is calculated by subtracting the total cost of the candies and chocolates (50m + 210n) from 1500.
