1 1/2= v + 3/4 (that's 1 and a half, not 11 over 2)<br> 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 :

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

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

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

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

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

What is the answer to 6(x+4)=30

DanielleElmas [232]

Start by distributing the 6 through the parenthses on the left side.

So we have 6x + 24 = 30.

Solving from here, I would subtract 24 from both sides to get 6x = 6.

Finally, dividing both sides of the equation by 6, we have x = 1.
