Question

The value of y varies directly with x. When y = 3 3/4 , x = 3/4

What is the value of y when x is 1/2 .

A . 1 1/4

B . 2 1/2

C . 4 1/4

D. 4 3/4

Answer 1

Answer:

2 1/2

y

Step-by-step explanation:

y = kx

3 3/4 = k × 3/4

3 3/4 - 15/4

15/4 = 3/4k

15/4 ÷ 3/4 = k

15/4 × 4/3 = k

60/12 = k

5 = k

y = 5(1/2)

y = 5/2

= 2 1/2
