1 1/2= v + 3/4 (that's 1 and a half, not 11 over 2) what is v?

Irina-Kira [14]

Answer:

The value of v is 3/4.

Step-by-step explanation:

First, you have to convert mixed number into improper fraction :

$1 \frac{1}{2} \\ = \frac{2 \times 1 + 1}{2} \\ = \frac{3}{2}$

In order to find the value of v, you have to substract 3/4 to both sides :

$\frac{3}{2} = v + \frac{3}{4}$

$\frac{3}{2} - \frac{3}{4} = v + \frac{3}{4} - \frac{3}{4}$

$v = \frac{3 \times 2}{2 \times 2} - \frac{3}{4}$

$v = \frac{6}{4} - \frac{3}{4}$

$v = \frac{3}{4}$

Katena32 [7]

Given :-

y varies directly as x, and y=14 when x=4.

To Find :-

the value of y when x=9 .

Solution :-

According to Question ,

y = kx ( k is constant )

When y = 14 and x = 4 ,

14 = k(4)
k = 14/4
k = 7/2

When x = 9 ,

y = 7/2*9
y = 63/2
y = 31.5
