Question

If x = 1/4 and y = 8 then how do you evaluate these expressions?

1. 3xy

2. 16x + 5y

3.
$\frac{y}{2x}$
4. 2(10 - 24x) + y
​

Answer 1

1. 3 x 1/4 x 8 = 24/4 = 6\1 or 6

2. 16x(1/4) + 5(8) = 4 + 40 = 44

3. 8 divided by 2x(1/4)= 8 divided by 1/2 (how many halves are in 8? = 8 x 2= 16

4. 210-24x1/4)+8 = 2 (10 +6) +8 = 2(16)+8 = 32 + 8 = 40
